Hi, recently converted from PT4 to HEM2 because PT4 froze on me all the time. Uninstalled postgresql and then installed HEM2 with postgresql. Imported about 1million hands and played a bit. So far it's crashed around 10-15 times already at different times; during import, during play, during me doing stuff in HEM2, no real logic to it. Sigh... Is there any way to improve the stability from my side?
