You may be running into this issue as the Paid Application is no longer being updated. As you did pay for this in the past, you can download the new application, which can be found through your App Store using the key words "SlingPlayer Free" and, so long as you have not changed your Google Play ID, you will be immediately upgraded to the Premium Service, which removes the adverts. Please give this a try and let us know if the issue persists.
I hope this helps!

samantha, thanks. i did download the "free' version and saw the
advertisements and figured that that wasn't the correct one to download.
i'll try again this evening when i get home and see if it will work.
thank you for the reply.
