Hello there Leslock, Sorry for late reply. We have been very busy last month.
You can try Graham's advice and see if it will fix the issues your currently having with your device.
Also, our Tech Team Lead just informed me via Skype, If you're techy enoughto do this, you can try to open a file browsing app on your device and navigate to /Android/data/org.xbmc.xbmc/files/.xbmc/userdata/ (the org.xbmc.xbmc folder may be named differently, but it should have XBMC in it still) and then delete the coreplayer.xml file there. Thanks!
