Emerald is not working in a friendly way, maybe a bug?

The way I think Emerald should work in is (for example I want to limit the downloading permissions of users for certains files):

When a user (not login in) comes to my website, he click on "download" menu item and find the file listing page (or detail page) . Then he click on the "Download" button, since this file only allows paid members download, he will see pop-up warning message and he will be redirected to the login form of Joomla. If he had already joined (purchased) that plan, his plan status will be verified automatically when logging in (this process is very quickly and the user will not notice that). After login in, there will be two different ways to go: if the verification is success (he has active subscription), he will be re-directed immediately to the download page, and the downloading will start automatically (because had already clicked on that "download" button); the second way is for those who don't have an active subscription: then he will be redirected to the plan list page (the best solution is to show only the one plan that related to that file he wants to download), then he can purchase the plan there.

Well, how does Emerald work now? It is (you can test it at my website with this file in my download system: http://www.joomlagate.com/index.php?option=com_remository& ;Itemid=48&func=fileinfo&id=1186 ) :

When a user (not login in) clicks on the "download" button, the page will pop-up the warning message and show the login form. Then, after he login in, (we suppose that he had an active subscription), he was not redirected to the download page, but to the plan purchasing page. My complaint is: what? Why show me the purchasing page again when I still have an active subscription?

From above test you can see that Emerald is not working in a friendly way.

Hope the developers will improve it and fix these issues.

Thank you.
