What did the debug log say?
Text wall gibberish coming up:

KoLmafia v14.8 r10111, Windows Vista, Java 1.6.0_26
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
Please note: do not post this log in the KoLmafia thread. If you
would like the dev team to look at it, please write a bug report
at kolmafia.us. Include specific information about what you were
doing when you made this and include the log as an attachment.
