Yes if you accidentally install/add to vp xml, it drops games and you lose part your list. I didn't back mine up after hours of work all lost. I have lost my motivation to redo it for now. It is a great frontend, I could never get Hyper pin to work i think it was because they release a 64 bit files and it wouldn't work on my 32 bit os. Best thing to do is create a new list and copy new tables from it to visual pinball xmls, Then pinx will count your games after you have reach 349 tables. This is a time comsuming hobbie and i think it is a shame a great frontend that saves you alot of work, ends up creating more work after 349 games. I am one who spends more time adding and editing tables then actually playing them it seems! I was up to 367 all VP, now back to 349 BOOHOO
