I have not watched slingbox lately. When I tried to I get a message that the Slingplayer for Web Application is not installed on my system and to click the link to download and install. I downloaded the installer. When I try to run it I get an error message that says it is not a valid Win32 application. I am running on Windows 7 Home Premium. It is a 64-bit os. The last time I used slingplayer on my laptop a few months ago it worked fine. I find this very frustrating. Can anyone help me get my 500 working again on my laptop? Thank you.
