Hmm, I may have missed something... I found this post (#7973) from Roy on 2+2:
It is almost always one of 3 things with Stars
1) You have not started Auto Import
2) if all your imports are showing up as errors then you may have a DB issue - email me at support@holdemmanager.net
3) If you are on Vista then make sure holdemmanager.exe and hmhud.exe have administrator access
4) Make sure hand histories are being saved in english
Even tho he's talking about the UAC/Admin rights stuff in #3, I brainstormed and decided to grant hmhud.exe an exception in my FW (which I had not done, just holdemmanager.exe). HM fired right up, and so far (knock on wood) it's working with no transport connection errors. Oh please let it be this simple! Will update in a few days even if it's fixed, just so you know. Thx.
