This is the wiki page for UF that covers at least some of the missing file issues and most of that should still be relevant on RoF2:

Basically, for any old zones you have issues with, just search the folder from an older client such as Titanium, SoF, SoD (and maybe an already patched version of UF) for all file names that include the zone name you are unable to access. Then, copy all files in the search results to your RoF2 folder. That should let you access those old zones without issues.
