Is it a Java Virtual Machine Launcher error saying "Could not find the main class. Program will exit!"? If it is, I have the same problem. Only on my computer I get the error not only when I try to use the uninstaller but also when I login to Windows. By the way, I have the basic verison, not the adware professional version so it's not like Limwire should be launching any software (ie: the adware software) at startup. The fact that I get that error at startup makes me wonder what Limewire is up to.
