I am running Windows XP on my desk top. Upgraded to 360V5 and could no longer connect to the internet via the wireless router. The error message indicated that none of the users of this computer were allowed to connect to the internet. Fortunately I had mirrored the C drive a month ago and connected this drive as the boot drive, so I was now running 360V3.8.0.41. I was able to connect to the internet with no problems.
