eLicenser woes

I have not opened Dorico for a couple of weeks, and this morning I was greeted by eLicenser issues.

I followed the recovery and maintenance flow, eventually arriving at the dialog that says:

The Soft-eLicenser stored on this computer seems to be altered in an unrecoverable way.
Please contact your software vendor to solve the issue.

Ok. Now what?

Resolved. Updated the eLicenser software. More strange errors on first attempt to launch Dorico. Second time worked.
