By the way, my Slingbox works on my Blackberry and Android phone too.
I called the Slingbox tech support. They informed me that since the Slingplayer worked on one of my devices, it was functioning properly and the fact that it does not work on 2 of my computers is my problem. The tech even watched my Slingbox from his office, putting in my username and password.
So if I only had the 2 computers that Slingbox did not work on, I would be out of luck and would be taking back the unit.
I wasted 2 days on this. When it would not work at first, I took the box back and exchanged it.
When I was initially setting up the second box and it did not work on my computers, tech support told me the box was defective and they would exchange it. Just for a lark I tried setting it up with my 3rd computer and it worked.
This is frustrating because my Sling Pro worked on my 2 computers before and just stopped working. 2 days later, I bought 2 new Sling Boxes and can now watch it remotely only on Facebook on my Vista computers.
I tired Internet Explorer, Safari, Chrome and Firefox, Nothing,. I think the webplayer plugin has a bug in it.
Not happy! Not impressed!!!
It seems that you are still having some issues in order to get the connection to your Slingbox PRO.
As you already know, the Slingbox is working fine. This situation allow us to narrow down the possible root cause to your computer. With this in mind, I encourage you check the following link in order to check the requirements for your Slingbox. Pay special attention to the Operating System and web browser versions, since the Slingbox will not work on Windows 64-bit browsers:
Hope this helps!
