Hi Playasjoint,
You seem to have done the obvious things. All I can suggest is that you uninstall again & make sure you take the "offline" installers. See here:

(It is an official version of LW? Not a scam one?)
If this all fails again, maybe try the new Beta (link in thread).
All the info from your options will go when you delete your preferences folder. That's what your preferences are. PITA, I know, but you'll just have to re-enter all that info.

Good luck!

**You know that you should only delete the pref folder when LW's CLOSED?
