Okay, first of all to those who will answer:
Do not give me shitty BS answers like the ones I had before. It's even more frustrating to give a crash log, detailed information on what I did when installing and get a copy pasted text from the support.
First of all:
More than a month ago, HM2 wouldn't load sessions in the scrolling menu under the Sessions tab. I was basically stuck with only one session. Everything was fine in HM1. I didn't really bother since this happened after a purge of database. I tought re-importing the old DB would fix this as I prolly purged incorrectly, I first tought. Nothing. The scrolling menu was still stuck with one session in cash games, the sit'n gos were loading correctly. Three days later or so, HM2 was crashing on opening. It could never be fixed.
I decided to use HM1 until the next update. When the update came (that's the Pokerstars HH change), it didn't fix. I started e-mailing support with a crash log. They gave me an answer that basically wasn't working. They asked me for the log again. They sent me THE SAME FUCKING COPY PASTED ANSWER with a different log. Pretty tilting considering I gave them a log of our exchanges. I still tried their solution, it didn't work.
I told support again, sent a log again and got the same answer as before, but this time written differently. Anywhore, this isn't the point. The problem is that my HM2 is still crashing when opening and nothing the support gave me is working so far. Their solution was to erase everything in roaming/holdemmanager folder except config and database and re-install.
Sowut naow? :/
I probably will have to ask for a refund if this isn't working at all. I paid for a pro combo and it worked only for a short period of time.
