PokerTracker

carbon (merge) did some updates and now when i start import says found 0 files to monitor???

You will need to configure PT3 to import from wherever they moved the hand history folder to - from what I've seen they tell you where your new hand history folder is as part of the upgrade.

I understand the new path should be something like:

C:\Users\YOURNAME\AppData\Local\CarbonPoker\history\
