The lifespan of the currently-available downloadable trial licenses for ASE Civil have expired. This was an unpublished, scheduled outage.
Fresh Trial Licenses Availability
The lifespan for these licenses will be reset to operate again within the next 7 days for an unspecified length of time.
We apologize for the inconvenience, especially if you were working on a project with your ASE Civil trial license at the time the outage occurred. Unfortunately, this interruption of license continuity is necessary to protect the interest of our clients who have paid full-price to use ASE Civil and also pay annually to maintain their competitive advantage.
It's definitely worth paying for.
