iCal file aggregation & Pro License issue

Hi. According to my Plugin status, I have a “PRO” license. I want to integrate online calendars in the the plugin, but the plugin tells me I have to buy the “Event Aggregator” add-on for this. When I click on the respective link to buy it, I only get forwarded to buy the “PRO” version to include the Aggregator function. There is no add-on for the Aggregator. Even if I did not have a “PRO” version already, there is no way to upgrade from whatever version I have right now to the version that includes the aggregation function. I submitted a ticket but have not heard back regarding this. It seems to be a trivial issue to me? Somehow the plugin side does not seem to know what the website sells. Can I get an update on this? I would need this fairly soon or I’d be forced to switch to alternative solutions.
