You will need to disable the pvr stalker client, clear cache in live tv, clear the guide also. Go to wherever you have your donation, iptv66, rocket etc... And do a iptv reset.
Go back into kodi, enable the live tv. You will get the "scanning for pvr" message and it should take you to the pvr pages, select stalker client and enable.
Go back to live tv and disable and enable again.
If all else is set up correctly then you should be OK
