First, thanks to everyone for their time and suggestions.
Decided to try another launcher (GO Launcher EX), which would buy me time until RLS3 is available. I remembered that I had TI installed and hoped to find a backup of Sense that I made after installing RLS2. Found it, restored it and rebooted and I'm up and running RLS2. There are some things that aren't functioning normally - can't go into Settings/Personalize, every reboot resets my home page, and I'm guessing a few others that I haven't found yet. I was able to make a backup of my Call Log, SMS, MMS, and pictures - the only items I was really worried about anyway - and will wait until RLS3 is ready.
Thanks again for everyone's help!
