Hmmm... A similar thing happened to me after loading the Strange library, 
except I was using another program, James Donnelly's FCAT, when the 
calculator died.  However, I was able to restore it from a recent ARCHIVE 
without any problems.

Are you certain C-Kermit was in binary when the original ARCHIVE was done?
I believe ARCHIVE always uses binary file transfer.  If C-Kermit was not
in binary, then the backup would not have been saved correctly.  I don't 
know of any way to recover from this, but then I haven't tried real hard.

I'll be very interested in what you have to say.

Good Luck!
