I know it's not a problem with the installer, because Limewire WAS working and then stopped.

I justr tried installing Beta.
Same problem. I'm not getting an error - but it does create the error log each time. Is there anything else I can try?

I know it form x-perience, i installed Windows Live OneCare, thinking it was going to be the total revolution for my pc's sec., and guess what, it didn't let Lw run, it was blocking all of it's petitions, uninstalled it and rolled-back to my old protection methods, and everything went well again, try uninstalling visual Studio for a while, and see what you got...
