With all due respect deepblue, it sounds much more like you have inadvertently installed some form of malware like a virus of trojan on your computer.

If however you are so sure that it is in fact limewire rather then another cause, perhaps it would be possible to post to the developers what the errors are and how you think it is causing them? It is much more proactive to report bugs caused by a peice of software then just simply stoping using it.

As well I have no idea what operating system you are running (I'm assuming windows) but perhaps it might be time for a reinstall of that. I find that windows 98 requres a reinstall ever 6 months, and XP every year--depending on how you use your computer of course.
