Download limit not working

Hi,

I have added the subscription management software, but its is not managing my download limits. Because I will have, for instance, 3, 6 and 12 month subscriptions, I would like each of them to have their own download limit. I set the various options in the component, but it only shows the downloads left as the download limit I have set in VirtueMart itself.

Without this, I don't see what this software does at all?

Please help, thanks.
