How do I remove an expired trial licence.

Hi,

Can anyone help me remove an old Soft eLicencer from my eLicence control center? The Soft eLicence was a from a crack copy of Cubase, which was already on the my laptop when i bought it a few weeks ago. I have recently purchased Cubase Elements 10 and tried to activate the Soft Licence, but it won’t activate because the old crack Soft eLicence is still on the system.
When i try to active my new Soft eLicence I get the error message “Upgrade failed. At least one of the eLicensers used during this process was disabled and cannot be used for any license transactions. Please contact your software vendor to solve this issue”.
I understand that the Soft eLicence is bound to my computer hard drive, but is there a way of deleting it? I called the German Steinberg helpline, who told me i would have to change the OS, but i fell that is a little extreme.
