Where is HEAT trial licence for HD 10?

Hello,

I'd like to try HEAT on my HD10 system but I can't find it on the Avid website. When you click on "free trial" on the HEAT page, you are redirected to a page where you can only select PT11 and PT HD11:

Of course, I've tried and selected PT HD 11 but it doesn't come with the HEAT trial...
You just get 4 licences : PT10, 11, HD10 and HD11.

I've tried on 2 different ilok account...

Does anyone know how can I get this trial licence please? Thanks.
