Few problems after Firewall Client

Hi

I installed Win7 and all was working 100%. Today i loaded Microsoft Firewall Client 4 to be able to use it on my office network. After installing i started to have loads of problems. First it was not booting it gave me a black screen after applying the password. I then booted in safe mode and removed the Firewall Client. I then can boot again but it is slow like hell takes approx half a minute and now i have no network onnections (Cable or wireless), can not enable or disable my windows firewall, can not vie event log and so on. How can i fix all this. And i was not able to do a restore from savemode or by the origanal cd.

Tnx allot

Did a sfc but could not find anything wrong and if i run a repair it tells me "The version of System Recovery is not campatible with the version of windows you are trying to repair."

It is the very same cd i installed it from. Windows 7 Ultimate

i do but first trying my options

Waiting to see what others say.

Why would fMS Firewall Client do this?
