I'm currently running into an issue where, following the summoning ritual into the next act, the game will give me one of two issues:

1. The game will crash, but I managed to stop this by disabling cutscenes and adding a resolution line to the config file.

2. Asks me for the Play Disc 3 error Play Disc 3, which I have not been able to solve.

Are there any workarounds for this?

Also note, I am playing on the 1.34A patch for the game.

Thanks in advance for any help.
