Dimok is at it Again!!
sorry about that but there was a bad bug in the cache invalidate function of RC1. I had to create an RC2. If you dumped any titles with RC1 you should definately re-dump the RPX and RPL files (/vol/code folder) as those are most likely corrupt.
Here is the RC3 with a fix for that bug and a cache buffer overrun bug:
Thanks to JaceCearK1 for reporting the bug.
