Licensing issue has been fixed as of 2:45 PM. Aspentech products should be fully functional.
ITS is aware of a licensing issue currently preventing AspenTech HYSYS from functioning.
The license expired this past Friday at midnight. We have been working with their support team since then to resolve the problem. They appear to have been closed for most of the holiday weekend.
We will update this post as soon as we have any more information.
