I'm not sure how it happened, but I have a file I can no longer open in 
DrScheme (version 4.2 [3m], Windows XP). I see the following error trace in 
a popup window when I try to open it:

insert-file in text%: error loading the file

 === context ===
C:\Program Files\PLT\collects\mred\private\wxme\text.ss:2538:2:

I've attached the file. Can anybody help me recover it? And do you have any 
ideas what may have caused the corruption, so I can avoid it in the future?
