ICQ has destroyed my webserver

No. ICQ was the only software which I installed! Before that everything was working!
The thing is that even when I unistalled ICQ the webserver was working! But when I restarted computer the problem occur!

First the message was that some other program is using same port as webserver which was the cause why IIS didn't work, but then I chagne the port and managed to start IIS but still I have received same error.

Then I have change the port to the original and IIS did run and only html pages were possible to see in IE or FF.

As I was reading other forums they have mentioned that when they installed ICQ they had problems with com+( Same problem as I'm having ).
They even had a readme/help file  how to fix it and I did that but no success.

I just reinstalled windows and it's working now!
