PokerTracker

I was importing a ton of hhs
approx 340mb of txt files, 1000 files total

it was on 393rd file, and i Just got a windows popup saying this porgram will be closed, do you want to send windows an error report, blah blah...

no PT3 error message or anything...

not sure what kind of info you guys need to look into this...
Is there a log file or something I can provide?

Please try importing the file that caused it to die again. If it crashes, attach said file to a support ticket: http://pokertracker3.com/support . We'll get it fixed.
