I have tried to export data to Excel (using Import/export to Ascci File), edited and saved the excel file. However when I tried to import the data back to Tilos, nothing happeded (i.e. no changes in current programme). Also the file type that Tilos allow to import is txt. file (not excel file). Is there anything I did wrong there? I was using the same function Import/export to Ascci File to import the file back). Many thanks
