If the program is installed it will not be gone when you reboot. There should be an entry for limewire in your program menu for you to start it again. It concerns me that you say you paid alot of money for limewire, the pro version is $18.88 and there is a free version, anything else and you've been scammed. It may also explain the major problems you're having with your computer. FYI, I also think it is against forum rules to post your email address.
