Internal Error

Hi;

I am working with Nois II 8.00 IDE, but whenever I want to run a project I receive the error like this:

COSIM: Internal Error (unhandled exception) in file cosim_main.cpp at line 140

Info : Exiting (null) model with return code 1 (0 fatal errors, 0 errors, 0 warn

ings)

I am wondering if anybody can help me in this case

Thank you
