Windows Server Update Services (WSUS) Error, Not Working

I had WSUS running for a few months when suddenly it stopped working and gives this error from the server any time I scroll to it in the "Roles".  

I've tried resetting the admin console as suggested, but it comes right back to the same error.  There are some other issues on the server revolving around IIS and certificates, so perhaps they are related.  The server is running on a self-generated certificate (if that matters).

WSUS Error Message:

The WSUS administration console has encountered an unexpected error. This may be a transient error; try restarting the administration console. If this error persists, try removing the persisted preferences for the console by deleting the wsus file under %appdata%\Microsoft\MMC\.

System.NullReferenceException -- Object reference not set to an instance of an object.

Resolution:

ASP.net has been set to version 1.1.4322 instead of version 2.0.50727 in IIS.

1. Start >> Run >> inetmgr
2. Open Web Sites and right-click on Default Web Site and select properties
3. Click on the ASP.NET tab and change the version from 1.1.4322 to 2.0.50727 and click OK
4. Navigate to %windir%\Microsoft.net\framework\v2.0.50727
5. Run aspnet_regiis –I
6. Run iisreset /restart
7. Navigate to %appdata%\microsoft\mmc, delete wsus

No go....v2.0.50727 is the only version showing under the ASP.net folder.  I ran through the rest of the instructions, but still have the same error.

Any other thoughts?

Also, this is on Windows Server 2008 - which varied a little from the above directions.

Latest update - I uninstalled WSUS in order to allow for updates on the local PCs.  When I tried reinstalling WSUS on server, received the following error:

Windows Server Update Services, Installation Failed
The update could not be found.  Either the update is not applicable to this computer or the update no longer exists.  Verify that the update still exists and is applicable to this computer from your WSUS server or Windows Update.
