Problem resolved.
I was using pro v 4.9
I bit the bullet and got the latest pro version and all is ok now.
It's a bit weird as the only difference I can see from the Limewire setup is the port no. Version 4.9 uses the 6xxx whilst the new version uses a diff port no. All Pc settings were not touched.
Weird.......
Thanks to everyone.
