bro brother,
MX-KEY never comes registered you have to register it before using and update license before using with latest version,if its coming with registration and working on only single version given its 1000000% fake its a copy MX-KEY no doubt about it and another most important thing MX-KEY IF U buy in bulk (50 pieces) then u receive at that price how come one retailer sell a single price at that price ,,so its not hard to believe that its a copy MX-KEY which comes registered and works with single version
but before blaming try update version and update license |
