Deactivation error code: -4212

I had downloaded the trial version. The trial period had expired.
Then I wanted to install the Community Edition.
But got the following error:

Activation failed with error: 0
Error description: No Error
License status: Server License Expired

I tried to deactivate the license using regutil.exe deactivate.
But again getting some error:
Deactivation error code: -4212, license status: 0, error description: SOAP invalid license number

Need your help.

I’ve been trying to get Rekordbox working with on another laptop. I deactivated the account on my original laptop then activated it on the new laptop.

Had major problems getting Rekordbox working on the new laptop even though it was a higher spec. High CPU, audio drop outs even when waveform set to low and latency increased to max and tried everything everyone else has on this forum with similar issues.

Any suggestions on this? I have the same error
