After 18 months of poker I finally bought PT. I'm uploading 12.6k HH and although the software told me it might freeze from so many, it has been frozen for 3+ hours now. Is this expected/Is there any better way to upload all of my hands?

I'm looking around FTR for a good guide to PT I stumbled upon a while ago but can't find it for the life of me. Also, what is this HUD thing I hear of constantly and where can I get it?
