Recently when I'm connected to limewire for about an hour or so an error pops up every second and it says...

"Limewire is unable to connect to hosts on the Gnutella network. This is most often due to firewalls or content-filtering software blocking access to Gnutella (port 6346). Please review your firewalls options to allow Limewire to access teh Gnutella network or speak to your system administrator or ISP to determine if Gnutella traffic is being filtered,"

and unless I'm at the computer to constantly close the error box every second or restart limewire from scratch, all the errors will pile up and freeze my computer and also force me to lose all my current downloads. I've tried everything that I know of including downloading the newest versions of Limewire, speaking to my internet service provider, and asking Limewire directly however all have not helped me. I'm not sure if this same problem is posted elsewhere in these forums, it probably is, but I can't find it and I'd really appreciate it if somebody could please help me fix this problem!
