Hm. Does your experiment launch any applications such as Powerpoint? What item-type does your experiment typically crash on?

It's quite peculiar that this bug is occurring.

Some further troubleshooting steps:
1. Try running the software as an administrator.
2. Make sure that you have full permissions to the folder: C:\MediaLab, as well as any locations where data will be saved.
3. Try and close as many applications as possible before running the software.

If the above steps don't help at all, there are a few other things we can try.
