Pokerstars update won't run when using F-Secure Internet Security 2012.
Had to uninstall FIS 2012 to run Pokerstars update. Turning everything off in FIS 2012 does not have any effect. Can run Pokerstars client though. I used FIS 2011 before and it didn't have this problem.
I have contacted Pokerstars support and they claim based on error number it is firewall that is preventing update, I have to agree with them because uninstall FIS is only solution I have found and FIS logs don't show any thing regarding Pokerstars update.
