2 problems:
1. Anti-virus
When I launch the Pokerstars client through Table Tracker the client starts OK, but McAfee isolates if3.dll every time. I have to open McAfee user interface and restore it. I have seen this problem being reported several years ago by other users. Maybe you should contact the anti-virus companies?
I also noticed that PT-Install-v4.11.11.exe had 10 positives on Virustotal.com (of 50 anti-virus programs). Locally on my computer McAfee also isolated this file just as it had downloaded. There was a file named partycommunicator or something within that .exe file that was problematic. Again I had to "unisolate" it from McAfee user interface.
In any case, I am able to launch the client and I log in.
2. Pokerstars error message
I do a search in Table Tracker and from the resulting list I right click a table and choose "Open Table". The table opens, but every time I get a pokerstars popup window that says "table initialization failed, low system resources".
The table opens, but this this error message every time will be a major annoyance, so I must solve the problem.
I doubt that low system resources is a real problem. This happens on every table I open, even if the client has just launched and I open the first table. Have never experienced any other performance issues with Pokertracker or Pokerstars.
Windows 7 Professional 64 bit, Intel Core i7..something, 12 GB RAM
I had the same problem before I updated to v4.11.11
