Unable to open a Show file

This is not the first time I report this issue. Even with both Hog4PC & HedgeHog4 at 3.7.1, I still have an issue with opening a file on Hog4PC. The software is looping at the opening, and I'm getting a message in the Event Log window like:
File extract failure for archive //sfm.ca/sfm/Home/GhyslainC/Documents/Flying Pig Systems/Hog 4PC/Shows/ACL 360i Test_bck.hog4show (system error code 2)

BTW, I just completely reinstall everything on my laptop, including Windows 7

Please help,as I can't always program my stuff on the board. I would like to be able to use my computer to prepare my shows!
