That is odd. Since 2.2.0.11 is the latest release version available via the CPF Update. Assuming you already have 2.2.0.11 (do you?), I’m not sure why CPF thinks there is an update available (because there isn’t).
The Update function within the CPF betas is disabled. So, it can’t be that.
This is a bug. You need to download the latest version (2.3.4.45) from www.personalfirewall.comodo.com then uninstall your existing version and reinstall.
Version 1.1.0.5 is the launchpad version not the firewall version, right click the system icon>>select ‘comodo firewall’ then select ‘open’>>select ‘about’ to see the version number.
