Hi Efrat,
I echo Josiah's comment. Is there a specific problem occurring?
Note that late stages of evolution for stars in this mass range are computationally expensive 
due to the development of off-center burning flames. So you might just have to wait.
Overall we can not really tell unless you send us more informations.
Cheers,
