I would like to save the model to keep working after, but I have the trial version (10.0.4) of the program. When I try to save, the Save option is grayed and I can't save the file. Can you help me?
In order to use all Stella functions including the Save option, you need to purchase the full version of the program. You can acquire it from the official web page. Its price is around $2499. For further information, I suggest you contact the developer using 800-987-6758 phone number or email@example.com email address.
