eLicenser problems

Hi, since april 4th 2020 I suddenly can’t use Cubase 10.5 anymore because the eLicenser shows me a message yjat the soft-eLicenser stored on my computer doesn’t seem to be created on my computer. I need to contact my software vender to solve this issue.

However, I haven’t buy or changed anything on my computer before this issue started.
I still use the same iMac running Mojave OS 10.14.6
And before that date everything was working fine

Can you please help me with this issue

Cubase Pro does not use the soft eLicenser anyway. Does Cubase Pro not start after clicking OK?
