LW Opens but locks up computer

[FireRescue57]

A friend of mine has had LW on her computer for a while now and just recently has experienced issues with LW. When she opens LW is locks up the computer and she's not able to do anything on the computer. So I took the computer and did a full system restore and reloaded all of the software that she had loaded on the computer before including Limewire. I was able to get LW to work while I had the computer at my place but once I returned the computer to her place LW wouldn't work and it would lock up like before. LW opens but thats all it does and then the computer just locks up....

Does anyone have ideas on how I can fix this problem???

What makes matters worse is I can take my laptop to here place and connect to her high speed internet connection and I'm able to open LW on my laptop and it works without any issues...

Frustrated...Please help
