Problem with xbmc 13.1 and redbull.tv - addon

[BeeHopper]

Hi,

i´m using xbian now for a few days. first with xbmc 12.2 (fresh installation of xbian). Streams and Videos on redbull.tv-addon started after buffering and run very smooth.

Then there was an update to xbmc 13.1 beta 2. Result: Streams on redbull.tv don´t start anyway. After restoring my backup and going to xbmc 12.2 the issue is gone. Back again to 13.1, same problem.

Is there anybody who has got a solution vor this?
And second question: How must xbmc be configured that a) only system-files will be updated, and b) NOT xbmc will get updates?

Thanx for your help!
