E-surge crashes when making result files?

[Alexlyon]

Hi

I have some troubles when using E surge to fit multi-state models.
My models should allow transitions between 7 observable states and 4 non-observable states (in which one dead state).
Actually the models run, and the optimization is achieved successfully, but E-surge seems to crash after running without giving results files (.txt and.xls).

First, I thought that it was because of the number of states (11), and the mark input format used which not allow for more than 10 states. However, as far as my data consist of only 7 observable states, the mark format cannot explain this crash.

Did anyone encounter a similar problem ?
Does the trouble come from the model ? or when building the results files ?

Any help will be welcome,
thanks in advance

Sincerly
