Hi, I had registered MorphOS 3.x years ago when version 3.x was released. I believe it costed around 111 euros at the time.

Yesterday I resurrected my dead Power Mac G4 (my old MorphOS machine) which had a dead PSU and today I decided to upgrade to Morph OS 3.14 and I did a fresh install losing my registration and now after 15 minutes use it slows things down.

What can I do ?

Contact support support@morphos.de and tell your problem. Think you will get your keyfile again....

You paid for MorphOS on that specific machine, not for the keyfile. The keyfile is just an enabler. You can't lose ownership as long as there is anyone still maintaining MorphOS.

As AmigaHarry2 said, just email the support and you should be sent a new one.

The quickest path to obtaining your keyfile again is to use RegTool. Fill out the form and in the Purpose field open the drop down list and select 'Resend keyfile'. You'll have to verify your email, but then can ignore the payment request ;)
