Fedor and David,
This is indeed a misunderstanding. The e-mail we received was requesting that we 'generate a license for the 3.0.304 RC eval installation'.
As the evaluation version does not require a license to function there was nothing to create. Had the request been for an extension I am sure the response would have been different.
As a support team we work to keep continuity between issues on the Discussion Forums, Customer Portal, and Extension/License requests so that these misunderstandings are kept to a minimum but as with many support issues the more information that our customers can provide us about the issue (that may reside in a different support portal) the better we are equipped to assist them.
Fedor you are always welcome to contact our support line at 1-866-847-7510 option 3 if you have any questions or feel that your support request is not being handled properly.
