Posting here because I don't think I'm going to ever get a reply on /vr/.
Trying to play Doom RPG with Roguelike Arsenal and it's monster pack, and when I try to load it using the launcher it gives me this error:

Script error, ":textures.txt" line 16:
Unknown patch 'MA75X0' in texture 'MA75Y0'

Script error, ":textures.txt" line 23:
Unknown patch 'WSTEX0' in texture 'WSTEY0'

ANIMDEFS: Can't find PMARA1

Execution could not continue.

Script error, ":animdefs.txt" line 7:
Unknown texture PMARA1

My .net framework is updated to the most recent version as far as I can tell, and I can't find any other solutions besides updating it.
