I have had that issue back when I used 7.1. Best advice I have is upgrade to 8... doesn't seem to have that issue anymore.
I did upgrade and I am using 8.3 as we speak, but need that code to save tons and tons of time!
Where are you saving your EG projects? If it is on a network drive then it will most likely be backed up and you can request a restore of the missing files.
This type of problem is a very good reason for always storing your EG files where they are being backed up like on a network drive and to store the underlying SAS programs separately from your EGP ones. An even better solution is to use EG with a version control tool like GIT. This is what we do and it minimises the chance of losing any project / code changes.
It's saved locally; not network! But it is a good lesson going forward!
It's finally time to hack! Remember to visit the SAS Hacker's Hub regularly for news and updates.
