When you get a ''Server Muted'' page instead of the ''qcbin'', Site Admin, or QC Client pages, it is usually related to DB or file system lack of communication.
In your case, since you tried pointing it to a DIFFERENT location for the repository, you need to make sure of a few things:
1) that the new repository folder exists,
2) it has the ''qc'' folder (which contains ''Default'' folder and other various domain folders if you have any), and a txt file (dbcon.txt),
3) it also has copies of the ''SA'', ''CustomerData'', ''import'' folders, and versions.xml
After doing this, start the services and Site Admin (everything else) should now come up again with IE.
Basically, you could copy the contents of the old ''repository'' folder to the NEW location.
Now, to get/move old/existing projects into the NEW repository location, you would need to ''remove'' them from Site Admin, move (or confirm they exist) the various project repository folders to the NEW location under the correct domain folder in the NEW repository folder structure, the edit the DBID.xml file for each project so it's Project Directory points to the new folder, then ''restore'' each project with Site Admin.
P.S. sorry about the superbowl.
