I can't connect
 

i just got limewire and i can't connect to the network. I tried deleting the preferences and i've tried reinstalling it. I even got the new beta version. Now i have some graph at the bottom of the screen and whenever i go to File- connect NOTHING HAPPENS!!! I have no idea what the problem is and i haven't been able to tell from the other posts if anyone else is having this problem. If you have any idea what's going wrong pleas help me. Oh and i don't know much about my computer or my connection to the internet except that i'm on a college ethernet connection. thanks in advance
