Help LimeWire isn't really user friendly - Windows XP

[cheetah400]

First I am having trouble getting additional sources. The message that I get is waiting for stable connection. Secondly if I try to cancel download and exit out of Lime Wire when I re-open the website the cancelled download re-appears. Thirdly as I perform new searches I recieve a message that Limewire is already connected to my network and I may not recieve a list until I am fully connected. All of this happen after I was in the middle of a download and i had to leave for a few hours. Upon my return I notic that my laptop had shut off due to low battery. Once I charged the battery and reconnected I have been facing the three problems described. Limewire is the only website that I am having problems with.
