I've just started playing at PartyPoker, and I've noticed that HM2 doesn't record the hands or results from MTTs or SNGs. The HUD also does not work, showing "waiting for hands". However, it does correctly import cash games.
I've checked the import settings and they look to be correct. One quirk: I'm in the HM3 beta, and it does work, with the same import settings as in HM2.
