It probably isn't as clear now, but with the CA Technologies acquisition the names and process has changed a bit. The Trial is the Community Edition. On the page I linked there is a note:
Your trial of this CA product is not time-limited, but it is subject to the following quantity and use limitations:
- Up to 10 Users
- Up to 5 Projects
Please let us know if you still have an issue accessing your previous Subscription.
Regards,
Michael
