samsung tv - spotify app stopped working

[11131437062]

I recently got spotify premium. It was working fine on my Samsung TV for 2 days. Now it's stopped. When I try to load the app, it just has a virtually blank screen with the spotify stripes. Is there a solution? Preferably without resetting hub/tv as I don't want to lose recordings from other apps. Thanks.

I have the exact same problem on my samsungTV, which is really annoying since I bough the membership and now I cannot use it. Where can I get support to fix this?
