[plt-scheme] Can't run Dr. Scheme

Okay, in case removing the preferences file does not work, can I ask
sasuke for a little debugging help? Specifically, can you open up the
file collects/drscheme/private/module-language.ss in the PLT folder
and insert this line between lines 104 and 105:

               (printf "default: ~s ~s\n" default
(find-library-collection-paths))

and then restart DrScheme and tell me what gets printed?

Also, I think I can provide you a patch to get your drscheme running
again, but lets see if the preferences file trick works.

Thanks,
Robby
