Directory Opus 9 Evaluation period nag screen

I'm trying to shift from Opus 8 to version 9. I installed the new version and there are issues regarding importing of version 8 configuration. That is why I'm delaying my decision to pay for an upgrade. During the evaluation of the new version I get the registration nag window pops up very often. If I leave Opus untouched the nag windows pile up one on top of the other.
This is extremely annoying.

Thank you

Request an evaluation certificate and the nag screen will go away for 60 days. This isn't made very clear in the text on the nag screen but you're running on a 30-day "stock" certificate which nags you until you request an evaluation certificate (which is tied to your email address).
