I`ve a problem using Limewire. I`ve installed Version 4.9.30 and it´s impossible using the proggie. Everytime i start searching something my pc breaks down and restarts automatically. There appears a dark blue display in BIOS-Style with this text:

DRIVER_IRQL_NOT_LESS_OR_EQUAL

I had the same prob with a proggie named azureus (bittorrent).
