I got (copied on clipboard) the license. Now. the instructions on the "Getting started with your new add-on" page are invalid for my (10 user) account. After locating the JGC add on I saw no option for uploading the .jar file that I downloaded. what was there upon clicking the "upload" button, was a LINK textbox. I pasted the link to the archive that I had downloaded and got a message to the effect that "your account cannot add this add on".
Now, I cannot even locate the JGC add on in the list (even after Enable Private Listings) anymore. The only "Gantt" entry found on page is the Gantt-Cloud, which I have (enabled; and don't like too much).
What can be done? our JIRA account is: https://artandindustrial.atlassian.net
