"the operation timed out"

Hi good people.
I have been running V1.37 on window 7 for quite a while, with no problems until 3 days ago.
I am behind a router using dsl and a vpn as proxy.No problems before this , ever.
I type in a movie name , in the box at the top right of the screen, click the green box with the white arrow ,and normally it opens up to all available uploaders , with that movie chosen .
I wait for maybe 10 seconds then get " the operation timed out" message, Is there a fix for this? what do you suggest?
Your help is greatly appreciated
