A "fake" run (a couple of minutes...long enough to get a gel file created)
using  more appropriate file names can serve as a "template" for ResEdit. 
Cut and paste the four resources that start with SS (don't have a file
handy, so I can't recall what the exact names are...the SS is symbolic of
Sample Sheet) out of the "fake" gel file and into the gel file with your
data.  Save, re-extract. 

Total recovery time...about 5 minutes.
