I tried this and it did not work.

1. Heres my solution that i came across...if you go to TOOLS and then OPTIONS and select the ADVANCED>FIREWALL CONFIG tab and select the 'MANUAL PORT FORWARDING' option.
2. Apply the settings and close the box.
3. Go FILE>DISCONNECT
4. Go FILE>CONNECT (This resets the connection...correct me if theres an easier way)
5. Go back to TOOLS>OPTIONS>ADVANCED>FIREWALL CONFIG and reselect 'USE UPnP'
6. Repeats step 3 and 4
