I just downloaded the regular free version of Limewire for the first time (2.4.4) and I'm gettng this same problem. It starts up, will even search and soemtimes start a download, but then will shut itself off in less than a minute. Im wondering weather it may be Win XP, looking through these boards Ive seen a few people mention problems with it, and XP seems to have some issues anyway. So, any advice on what I can do to get this up and running?
