According to the error it says..
Due to some unknown problem, Windows cant show Firewall configuration
Not that exact words.. but something like that..
That was showed when i clicked (Firewall de windows)
Edit:
Restarted in safe mode and it aint working
Im going crazy
Edit2: Lets wait until Cookie or someone that wants to help reads my post..
Edit3: Ok just found this website
http://windowsxp.mvps.org/sharedaccess.htm
seems like that can help me..
Edit4: Just searched for my problem (Google is my friend) and found that page like i said, its fixed now.. I guess sharedacces.reg got corrupted when i installed Bitdefender antivirus..
