I get the not supported error DE90-64c8 code 23 when trying to run the slingplayer app.In a previous post it was replied that this meant the slingbox was not supported. I do have several slingboxes that I can choose from to connect including the pro HD, which does have the updated software. I did get a conncection a couple of times but am no longer able to. Could the app be trying to connect to a box that does not meet the criteria? Is there a way to tell the app which box to connect to?
