Comodo broken after aborted update

I accidentally broke off an update by turning off the computer (I forgot it was updating) and now Comodo reports the firewall is not installed.
I have tried to uninstal but that froze. Just like my attempt to just download the latest version and instal that without uninstalling it first. It just stops at 90%

What can I do t fix this? I am running windows 7 by the way.

(please excuse me for any bad grammar. English is not my native language)
