Error 1603 - back again ;/

Hi all
First og all, id like to say that Comodo was a great, no wait- the best free firewall ever! ... until new version :( I had Comodo Personal Firewall Pro installed half a Year ago, uninstalled it and went for Panda Global protection 2010 for halkf of the year (from a pc magazine). Now my subscription has expired and i want to get back to comodo but cant!
I tried the comodo cleanup utility programs, searching for registry problems and so on and got nothing!

can someone please help ? :frowning:

What is the alert you are getting when trying to install Comodo Firewall?
