I will try that. I also keep having problems with websites-I can usually access them, but when it comes to downloading or uploading something, it freezes up. Could that be related to my current problem?
I am also getting this warning in application event log:
Event Type: Warning
Event Source: WinMgmt
Event Category: None
Event ID: 63
Time: 6:26:32 AM
A provider, OffProv11, has been registered in the WMI namespace, Root\MSAPPS11, to use the LocalSystem account. This account is privileged and the provider may cause a security violation if it does not correctly impersonate user requests.

Thanks for all your help!
