Custom Kodi builds can add all kinds of problems depending on the functions you are using (PVR Clients etc.)
They usually are missing or have modified dependency modules that dont mesh properly.
So, you use at your own risks.
....that said, when you make a change like this with Stalker and MAC# authentication, you should change your MAC# linked to your Donation to a new #.
Then make the change to your Stalker settings, and change your Dev ID1 # also.
This is basically a fresh start setup in the Server, so when you first login, you dont have any problems with remnant info from your old setup.
