Hi --
I was having various BDTS 2009 issues, so browsed here and saw several posts saying basically, "Why not just upgrade to 2010?"
I ran the uninstall tool, and all goes well until it "Fails" to fully delete "Delete main registry keys". I let the tool run all the way through until it prompts me to hit "Close" or "Restart PC".
I've done this now several times with the same result: I have no BD on my computer, and can't install the new one (or even 2009 again, for that matter) -- I'm in "limbo" here...
I've run 2 Registry Cleaners: EasyCleaner & CCleaner -- same thing. I really don't want to have to do the "System Restore" thing... 
This particular PC is running Windows XP and is a 32-Bit system. Plenty of storage space, plenty of RAM, etc...
So... Help??!
Thanks a lot --
