Ok this is extremely weird... but I just thought I'd keep you updated.
Since my last post in this thread I had given up and decided to quit installing, uninstalling, reinstalling over and over again. So let's see..that was about 5 days ago? Yes I experienced withdrawal symptoms :P Don't worry I'm slowly getting to the point here.
Anyway, 5 minutes ago I decided to give the installation another go, being hopeful.
You know what? It's working perfectly.
Unfortunately Squirtukuk I don't have any advice to give you as I didn't change anything about my computer.
I just hope this never happens again. I'll never take Limewire for granted again
Thanks to those who tried to help
