I'm assuming you have an Android device?
If so, it sounds like you are launching from an imbedded app on your phone... If you go into Google Play (formerly Android Market) you can find and re-download the regular SlingPlayer application.
Sling offered a special deal to Verizon customers that included a Slingbox 120, but since you already have a Slingbox, you can just download the regular Slingbox App.
Hope this helps,
