Access level, subscriptions cant save, file not found

Upgraded to premium and now both access level and subscriber level will not save it says "page not found"

When I click on a level on the membership page I see the page and the subscriptions data but I can not change the access level limits.

I have reinstalled, re run the membership wizard several time, deleted those files as nothing will save "page not found"

ID numbers no longer match level-level-id1 is id 22

how do I fix this please
