Link shows my license keys. I'll send you a PN.

They're of no use to anyone else... the key is hashed with your serial number so is unique to you, nobody else can use/abuse it.

I think this is exactly what happens here. Interestingly my own builds don't show that error on startup when I only disable CEC by addon. Thanks!

My builds are using additional libcec patches (as detailed in the relevant release post) - it's possible one or more patches don't play so well with unusual CEC configurations.
