Retroarch not launching for iPad. Failed to create or access

Has worked great for a week. Now it launches with an error “failed to create or access base directory: /var/mobile/documents”

I double checked all my ifiles and even deleted and reinstalled retroarch and got the same message. What else could be my problem?

Sounds like a permissions issue. Check that the directory ‘/var/mobile/Documents’ exists (the capital ‘D’ is required), is owned by the user ‘mobile’, and has Read Write and Execute permissions for user.

That fixed it, permissions. I just don’t know how they got changed, I never go in there.
