HI Guys,
I'm pretty new to the p6 Program and I'm only just starting out as a Junior project planner. On my second week now and I've all ready managed to currupt the program...lol :-(
When copying and pasting an Activity with relationships I seem to be getting an SLDNA-0655-B error message. Obviosuly I've exited the program and restarted it, however the problem still seems to be there.
SCREEN SHOT BELOW.

If any of you technical experts can offer any help, would be more than appreciated.
Cheers,
Tom
