Hi,
In order to post on any of the "Pro" boards (marked (*) For registered customers only) of our forum or download attachments, you need to be logged in with user credentials linked to a "Pro" license - you can associate any forum account with the "Pro" license account under User Panel - Forum - Forum Accounts. However, I have just granted "Pro" permissions to your forum account "RD0589", so you now have full access to the Pro boards and should be able to post and download content from them.
I hope that helps.
Best regards,
