Damian is correct, this is a common problem for the new users of optisystem. Generally in optisystem forum ,most of participants use latest version of the software and post simulation files. However, you cannot run advance version file in older one. If you facing problem that you have no access to new version or it is expired. Then you can extend license by contacting optiwave or ask for screen shot of the file , so as you will be able to make it in your version.
