Hello,
Thanks for reaching out to us!
Would you mind sharing the screenshot of the error? Also, can you please try to reboot your system and see if it works?
If not, then uninstall the OptiSystem and reinstall it. Once it is re-installed, then reboot it again.
Let me know if this works?
Also, please send us the screenshot of the following links:
