The only thing I have found wrong with player notes is that they are saved on your C:\drive.
When I got my new PC, wiped my HDD and reinstalled everything, no more player notes!! (Not that any of mine had to do with how they played poker

)
If its any help to anyone, your VC notes (and maybe all Tribeca skins) are saved in C:\WINDOWS\PlayerNotes (or they were!)
