OM3 Activation Problem

Hi.

I've had to reinstall OM on a new old machine after the new one died unexpectedly. I downloaded the latest version and installed it. At the Activation screen I enter my key and hit activate and it fails with

In FORMAT: Missing argument:
  "Error when checking license:
In FORMAT: Missing argument:
  \"License ~s got error: ~s\"
                          ^"
            ^

This was previously okay but now not so much.

 .. mark.
