PokerTracker

The error window says, "Exception occurred while processing hand history file", the HUD occassionally freezes now on 1-2 tables.

What site was this for? Have you tried stopping and restarting PT3 since the error?

this is for PTO/pokeracehud and it occurs on stars. I've tried restarting acehud, and it fixes the problem for awhile.

In that case, please enable logging (Tutorial: How to Create a Log File) and attempt to play for 30 hands on a single table while importing, and then attach the PAHud.log file to a support request and we'll look into what could be causing this for you and help you get the issue resolved.
