evaluation version limit exceeded for q devices!

I downloaded a mod LM6172 and added to library

Then, I built a small circuilt which is a voltage follower.

After I clicked simulation button, the error came out.

ERROR -- Circuit Too Large!
EVALUATION VERSION Limit Exceeded for "Q" Devices!


I remembered two years ago, I used student version to simulate a omp, it worked. Why I got the error message this time.

It is possible that the model of the OP you are using has a discrete implementation (a lot of transistors inside the model). Try with an other OP, a simpler model will work.
