Can anyone help???????? PLEASE

I have been using lime wire for 6 months never had any problems installed all the updates as and when required.

I use windows XP and have 1 meg broadband

I used to be able to leave downloading all night.

A bout 2 weeks ago LW started diconnecting for no reason after an hour or two.

I have since installed LW 4.9.33 also but now for no reson LW is just disconnectting after less than 5 mins.

I have scanned for viruses checked my settings.

I have not changed or altered any settings.

Can anyone please help me as to why LW is torturing me like this and how to solve this problem.

Thankyou for your time.
