Hi all,

 I recently downloaded the student version of Chemkin-Pro 19.1 because our academic license ran out and we did not want to renew. I am having issues when pre-processing my mechanism (ones I have used before sucessfully on Chemkin-Pro 17.0 in the academic license). Below is the screen shot of the error i am getting which is not super helpful for diagnosing what is going on. The mechanism is the Aramco 2.o mech which is fairly large, could that be the issue?
