iMac Connection Problem
 

I have a new iMac, and I recently downloaded Limewire. The program ran fine until a week ago, when I was unable to remain connected for more than 1-2 seconds. I also purchased Limewire Pro, but if I'm unable to use the program then I want my money back. I have a T1 connection, and I'm at a university. However, I did not have problems until one week ago. Also, I have read other posts of people having the exact same problem as me, so I don't think it's due to my connection. I want a refund of my purchase, and when the problem is rectified, I will repurchase Pro.
