All the members of the Club Poker forum (french forum) who installed the beta client are unable to run a single tracker (HEM or PT). Winamax even said that they were aware of the situation. Do you mean that your Testing manager was able to run HEM 3 with the beta client ? Thanx.
I changed the path to the new folder.
OK, I'm having the results ok sessions now, but still no HUD...
HM3 v18.104.22.16805 is now available with added support for new handhistory folder after Winamax client update.
You can find the release thread here. Beta is available through auto-update if you are opted-in for beta updates.
