Please check the user manual first (EN/DE) and find the knowledge base and answers to technical questions in the FAQs of the former eBlocker GmbH. Mac and iOS users please read this article in case of certificate issues.
Found a website with the errorcode and "Schlüsselbund" issues, but the outgoing link to the apple discussion forum is not working.
It is an issue with the keyring store, could not been read or add anything.

Try to backup/export the keystore and delete it afterwards.
Then recreate it and try to import the certificate
Hope this helps
Screenshots from License and Update Screen and certificate
I also have another certificate with "*.cer" instead of "*.crt", but when I tried to make an upload there was a message that this is not possible at the moment.
I found two certificates in the keyrings but I'm not able to delete them and try it again. (see in keyrings.pdf)
No visible error in the attached screenshots..
So please go through the websites I posted, regarding the keyring issue in MacOS...
As I don't have an Mac, I am not able to check this issue any deeper as I've already done.
Good luck
Cheers
Sven
