I haven't downloaded or changed anything on my computer, and one day out of the blue, my LimeWire stopped connecting (it has the one bar connection, and it's next to the firewall icon). I have looked at the FAQ and have done everything to try and solve this problem in the FAQ, but nothing has worked. LimeWire is listed as an exception on my Windows Firewall, and I tried deleting it and re-adding it, to no luck.

I run a cable modem (through MediaCom). I have a Linksys Router Model No. WRT310N (UPnP enabled). I have Windows XP. I have like 56 GB of space left. I have not downloaded any new software that would impede LimeWire from working; this all happened out of the blue one day. I don't have any anti-virus software besides what my Windows Security provides. Any help would be greatly appreciated.
