Most everytime I open the latest version of Limewire (downloaded yesterday), it locks up my computer when it goes to connect to the internet. When I get it unlocked, I have no access to the internet - I'll close Limewire, but even my browsers (Netscape or Internet Explorer) can't connect.

One time, my monitor just went to the "press Cntrl-Alt-Del" note to restart or press any button to go back" note.
Multiple times, my computer restarted on its own, as soon as I pressed "Connect" from the "File" menu.

I have a cable modem, and use Windows 98.
