TINA/Spice/OPA1611: getting a "circuit too big" when trying to simulate a circuit with more than 38 OPAs

Tool/software: TINA-TI or Spice Models

hi

so i happen to need to simulate a circuit with over 50 OPAs in TINA TI, problem is, when i put over 38 OPAs in, i get a "circuit is too big"
anything i can do?
if i get TINA11, will it be able to run such a massive circuit?
