For anyone having problems with there skin when updating to beta2 just go into the skin's addon.xml and change the xbmc gui from whatever version it was previously to 5.17.0 for example xbmc.gui version=4.18.0 change that to 5.17.0 (xbmc.gui version=5.17.0) and thats it the skin will be read/used and it won't be disabled when starting up Kodi for the first time when installing beta2
Der Tip funktioniert gut, habe gerade den alten Confluence skin so wieder zum Leben erweckt. Danke dafür!
