I highly doubt that. Apple software doesn't care..
I was referring to a domain controller using group policy( a windows program on a windows server OS ) to disable your ability to use iTunes.
Also, are you entirely positive that you are on an adminstrator account?

YI - Finally found the issue, I had to select my login/user folder under C:\Users and go into the advanced security settings and validate that I had Full Edit priveledges. Even though all the iTunes folders looked ok, I had to go to this level of folder permissions to fix it. Thanks for all the help!
So try that. The folders you are saving to / opening aren't getting proper permissions to read/write. Add read/write permissions to all itunes folders, I'd say.
I can't tell you which ones specifically as I don't use the software, however.
