@Germania I extrapolated from Faqs | How to deauthorize your license from the current computer? (dvdfab.cn)
0xFeedBeef
The only new for me is
[quote]deauthorizing all computers option can only be done once a year[/quote]
but that only has to do with the fact that I didn't care at all before SF 6221
I know how to deauthorize in SF ..
[quote=Germania;n459215]but it also means that I can't (more) deauthorize the blank Mac with SF 6221 itself[/quote]
I think the only way to deauth the blank MAC (from SF 6221 initiated and still there)
is only possible in Member Center - already done in my 1st post !
But deauth my 2nd created blank MAC (useless in future) force decrease counter (5-1=4)
So I'm disadvantaged for an error in SF - That's the thing.
It can't be that difficult to remove all authorizations with an empty MAC
in the database using SQL (without the counter becoming active)
