I have a student who after several hours working on his program, tried to reopen it only to receive the error below. Is there any way to recover from this, and get his project at least editable? (another computer definitely didn't solve the problem) Any ideas what causes these problems, so I can tell students what to avoid in the future?

I forwarded this to the admins.

They've fixed a few worlds like this one before. Hopefully they'll be able to fix this one soon.

Sorry about the trouble.

Download the new Alice 2.3.5d release.

:confused: I can only assume that you mean the current Alice 2.3 download from the web site. Where is the information regarding what SPECIFIC changes/fixes were made in a, b, c, and d? Thought that to be Standard Industry Procedure.
