I have been using Slingplayer on my desktop (using Vista and IE) for a couple of years now without any problems. I'm in the USA and the Slingbox is in England.
When I try to connect to the same Slingbox using my laptop (Windows 7 and IE) I cannot connect to the Slingbox. The only difference is that I have the latest Slingplayer version on this laptop unlike my desktop.
It is not a browser or Operating System issue.
I also turned off my Anti Virus software.
I can see my Slingbox online and through the Slingplayer program it just won't connect to it through either medium.
If anyone has any ideas then I would be very grateful.
