I use HM for a few weeks now, and I'm very content with it. I only play MTTs, and the HUD is my main interest. I play on all major sites.
The problem is that with Titan (iPoker) I usually dont get any stats. Only when I play MTT qualifiers I get stats. The other tournaments show up in the table manager list, but no HUD. It stays on 0/10 players. The hands are imported into the database though.
This behaviour was there since I started using HM, and never changed. I always use the newest version from the releases part of the forum.
I saw some threads about people having no stats after being moved to another table, but I dont get any HUD stats at all (except for the MTT qualifiers).
For testing I tried playing cash tables at Titan, and there the HUD worked flawlessly.
