LMS 7.8 - Spotify error

[ajs6000]

Updated to LogitechMediaServer-7.8.0-33924 and Touch fab4_7.8.0_r9702.bin

I get the following error for every track:-
Slim::Plugin::SpotifyLogi::Plugin::spds_handler (220) Spotify error, code 10: Spotify streaming error: General permanent error

Restored system back to LogitechMediaServer-7.7.3-33913 and Touch fab4_7.7.2_r9694.bin and Spotify works fine again.

I tried this on 3xTouch's and 3xControllers with the same result.

Server OS = Windows 7 (x64)
