''The launcher not being able to access the custom ogg folder seems like permission issues, did you run the launcher as admin?''
''did you run the launcher as admin?'' ''run the launcher as admin''
Oh boy don't I feel STUPID right now. Ran as admin and all my life problems were solved. PSOBB is back in place and the update is going as normal. I'm sorry for wasting you time with this absurdly easy to fix problem, but still, thank you SO MUCH. I can't wait to play this again.
