Whenever I try to start pchelpware on the viewer pc (I have previously created direct connection .exe) I get error: bind failed.
I've noticed when I hit map UPnP I get: Internet Access Server -- WRT5 and below it Unable to add mapping. I have port 5500 enabled on my router and I have tried also with UPnP unchecked but I still cannot get it to work. Very strange. Any idea's what I need to do/try to get it working?

bind failed --> port in use by other application

Re: Error: Bind failed
Ok thanks for the reply. It must have been Ultravnc using it. That has sorted my problem. Turned UPnP off also and it works a treat now. Now to delve into tweaking the apperance. Thanks so much for the help.
