error:Unable to open storage set. make sure the file exists.

Sometimes, when I save a model, it gives error message:Unable to open storage set. make sure the file exists.

any idea?

This is an error message that was related to a system we put in place a while ago. The system was supposed to allow users to mark models as read-only. After using it for a little while, we decided that it was no longer required. Unfortunately, in order to maintain backwards-compatibility with older models, we had to leave a few of the commands from this system in Flexsim. We'll make sure this message does not appear when you are using version 4.5.

On the other hand, when you get the message, does it still save your file? A few other people reported this a while ago and realized that their models were still being saved correctly. They just had to close the message window whenever it appeared. It was an annoyance, but didn't actually stop them from working.

Yes, it still save my file.

That's good news. At least you're not losing data. Have you installed the 4.5 beta yet? If so, do you still have this problem? Please let us know if you do. Thanks.
