Sir, I am a final year student, doing my 4th-year project on MathCAD, I am referring to a paper which also used your software hence I gave it a shot too. I have finished my 30-day trial and my college promised me that they will get the license, but it doesn't seem to be the case anymore. The code uses functions not available in the 'Express version'. I am from a third world country and there is no chance my parents are going to let me buy the software. Is there any way that you can make an exception in my case and lend me a license for another 2-3 months while I can finish my project and submit it for my final year. I can share my source file with you for you to verify the work I am doing. I will be grateful if you could help me out.
