Joy,

Initially, the corrupted files were detected last March. I contacted Primavera Technical Support and spent several hours on the phone while they walked me through how to batch the project file to remove corruption.
The second time the corruption was detected, last month (July), I e-mailed the project file to Primavera Technical Support, requested they batch to remove corruption, and save with XER format so I could transfer into P3e. Incidentally, the second time the corruption occurred, it was on the same file that had been "cleaned" in March, but with more activities added since March. After receiving the project file back from Primavera, I imported it into P3e. Primavera cautioned me to not open this file into P3Win because it might become contaminated again.
I have installed P3e on my computer and took the 3 day training class several weeks ago. Since I have been a Primavera user since it was in Dos, I have found the transition to P3e easy. The switch to P3e seems to have solved this problem as I have imported the "clean" project file into P3e, have updated it, and have had no problems. Everyday use of P3Win had become slow because simple things such has printing out schedules took much longer than normal. So, besides activities defying logic when I updated, it had become time consuming to even print out a schedule. It seems then, that the incompatibility issue between P3Win and Windows worsened as my schedule size grew. One Primavera Support Technician told me that the incompatibility issue between Windows and P3Win is minimal when the schedule is small, but as the schedule grows in size, the issues between the operating system and the software become much more obvious. If I can help with this any further, just e-mail me and I will forward my telephone number.

The solution to my problem has been to make the transition to P3e. The issue appears to have been an incompatibility problem between Windows and P3. P3 Technical Support alluded to this, but no one really knows and have no way of finding out. I have taken the 3 day course in P3e and so far am glad I have made the move. Although I will probably encounter nuances with P3e as I progress, ultimately the corrupted file issue has been resolved and so the saga ends.

I am wondering also if my problem is due to missing or corrupted Windows operating files. I am at the point of making the switch to P3e/c even though I prefer to stay with P3Win. If I can’t figure out the problem I don’t know what other choice I have.

Yes, I have sent the file to P3Tech Support to batch and render clean. I have the last P3 service pack installed as well. Our IT department does not think it is a hardware issue. This is the only machine we have loaded P3 on, so possibly it is a Windows issue on this machine or a hardware issue, who knows? I should receive the batched files shortly and Tech Support has advised me to import into P3e/c and then do any restoration of codes, logic, etc. If I load this file into P3e/c and still have corruption I’ll have never left square one. I will definitely share the solution if we can ever find it.

I am the only user and it is a stand alone version on my machine. I also have not been able to open multiple projects simulatenously without P3 locking up and automatically shutting down. I have gone through the re-install process for P3 previously, but nothing seems to prevent the corruption or the lock up problem.

I ran the batch on this file when corruption occurred previously and then ran P3fix everday afterwards. Unfortunately this has not fixed the problem. Last time I had the batch run it deleted activity codes that I had to re-enter. This time the corruption is causing the schedule to ignore the calendar and logic and has caused the colors on the screen to be different than the printout. I talked to P3 tech support again this morning and no one has an answer for what is causing the corruption. It does not appear to be a hardware releated issue as I have no other problems with any other software. This appears to be an anomoly that no one has ever experienced nor knows the answer. Thanks for your input.
