I skimmed through the ML threads, so I hope I didn't miss a thread where this issue was already addressed.

I have a weird problem with DRT files that I've never encountered before, even though I've used ML to administer DRT files many times. I have a ML EXP file that contains two DRT tasks, and whenever the program gets to the second DRT task, it provides a warning that the subject number has already been used and that the data will be overwritten, even though the subject number has definitely not been used before the session in question. What ends up happening is that the data from the second task overwrites the date from the first task -- despite the fact that the QUE files have different names, are linked to different CSV files, and have different item names within the QUE files to link to the CSV files.

Any ideas?

Thanks,
