Forced reinstallation, Firewall stopped working.

Hello y’all.

A couple of days ago I was remoting to my server (running Comodo Firewall 2.4 under Win 2k3 server) and all of a sudden a popup displayed that Comodo Firewall has stopped working and it should be reinstalled. No message of why it did so. In my stupidity I uninstalled the firewall and reinstalled it. That of course kicked me out of my remote session. So my question is: Since I can access other servers on the same net as this particular server, can I in some way configure the Comodo Firewall to accept Remote Desktop connections, etc. The status is right now that nothing can access the server and the server can’t access anything either. I know its up and running but I just can’t do anything with it =(

Thanks in advance
