Trial License and limits in student editions Good morning,I have 2 questions.Last July 14th, I downloaded and installed Mathcad Express with a 30-day trial license, but today it no longer works and seems to have expired after only a week. Is there any workaround to continue with this 30 day trial version (I have downloaded a new license file, but everything remains the same).On the other hand, I am a professor at the Polytechnic University of Catalonia (Barcelona - Spain), and I wonder about the limitations that the student version may have, compared to the full version.Thank you very much.
