HELLO DHIMAN..
you are welocme anytime…I am posting the link where you could go and upgrade your license to version 14.. first i would suggest you to uninstall the evaluation version and just stick with your licensed version 13 of optisystem…then follow the link where you would find another link under the heading “Active maintenance & support users may upgrade their license here”…just follow those steps and i hope ur issue will be resolved..
