Port number issue

A usage of Studio instance with the same subscription information was detected at 192.168.0.164 @ 192.168.0.164.
A concurrent usage of multiple instances is not allowed by the license agreement.
Close another Studio instance and continue your work.
How can I solve this.

Regards

Hi,
The error means that several Studios registered with the same license key are running at the same time.
It is forbidden.
Stop the second Studio instance or disable premium add-ons in the project which you want to open.
