Can you upload the model so we can take a look? It could be a number of things that is causing this.

It only runs to 2 as you have a floating point error which stops the simulation.

Given the size numbers you are dealing with, I'd suggest converting them to "million people" instead of "people". This will probably fix the floating point error.

The likely cause is a division by zero or runaway exponential, perhaps from a feedback loop with the wrong polarity.
