Unable to connect to internet or access anything through router. Also, when starting windows is now asking me to register my copy of the operating system which is currently over 2 years old (installed with Parallels 3.0 in 2007). I have tried going back to a previous snapshot and this works for a 1 time connection to the internet or router. When I try to access through router again I am unable to connect. I have tried repairing the connection as well and this does not correct the problem. The Network Connection shows the connection is good. All connections on the Mac side are working fine. I am fully updated on the Windows and Mac OS. I only use Parallels to run my architecture software Revit Architecture and Adobe Acrobat Pro 8. What is more unusual...If I find a Revit file through Finder and open it, the file will open in Revit. Meaning it appears the connection is broken from Windows to Mac not Mac to Windows.
