Great. The missing files were on the 2013 upgrade disc one. I actually re-installed all of the RTs from both discs.

So there are still 4 genuine missing (N/A) RTs from the list as they were part of a 'bonus' pak Country Waltz. Even the tech at PG support was missing them. Also...even with all files loaded / rebuilt/installed, if you choose show only N/A tracks then it will say 425 items in list even though none are missing. This is what I have and what PG support both had. Who knows why. But all my tracks/items are there verified by properties.

Have a great week yall! Appreciate the help.
