PokerTracker

Hi, before I continue I'll say that I'm impressed at how diligently this app is handled by its creators.

Got this error after purging 2 sessions. Think I messed up my database and I can no longer import hands without it freezing.

That could suggest a corrupt database - that shouldn't happen unless your computer shut down (or slept) during a database procedure, but it can happen if you have a bad disk sector too for instance.
Please try the suggestions in this guide.
If that doesn't help try this.
Failing that you may need to create a new database and reimport your hands using Get Hands From Disk.

I tried both steps but keep getting errors.

I'll create a new database, all good. Thank you
