We actually got a reply from Tech Support over the weekend, but 
unfortunately it didn't help any. Their only suggestion was to reset the 
init.m files, which we had already tried, before resorting to 
uninstalling and removing all Mathematica folders completely -- and even 
that didn't help.

If anyone has any insight, it would be much appreciated.
