Having issues decrypting 3 of the 4 discs in the set. The program starts it's initial decryption then goes into an endless cycle of detecting corrupt or invalid offsets. I've let it run for 30+ minutes with no progress. I can't get a log of the process since it never actually stops trying to process the titles. Is there a known issue with this set?

If you have debug logging turned on, a text file will be generated with more detailed error messages.

Most likely problem is disk contamination. We even have a topic about that at the top of this forum.
