I'm a student and using the Xpress IVE 8.4.4. I made a deterministic model and everything was working fine.
Now I want to change to a stochastic model so i downloaded the Xpress-SP module (Xpress Open Source - Box ).
However, when i want to use the mmsp i always get an error:
Error 302 - The symbol 'getobjval' from 'mmsp' cannot be defined (redefinition).
Even when i try to run a nearly empty model, this error pops up.
Also when i try to run one of the example models that are included in the SP module, often i get a notification that it is unsafe to continue so i have restart the programm.
Does anybody what the problem is, so i can use the mmsp?
Thanks in advance!
