Aloha. Having trouble importing a device file into mx-editor v14. When I select on the available devices (oppo in this case), a Device Assign dialog box opens with several Used External Devices listed in this case. However, I can't seem to select any combination of dropdown choices and highlighted External Devices that will enable the OK select button?

Every few months we see this very question, here is my answer to another post a few months ago about the same thing

You need to assign each of the devices under 'Used External Devices' to a device under 'Assign Device To' before the OK will be available.

Select the first one in the upper list then click something in the drop down list. Now select the next one in the upper list then click something in the drop down list. Do this for EVERY device in the upper list, each one needs to be assigned before the OK button will be available.

This is caused by punch throughs being set in the device when it is exported. Make sure you double check your punch throughs after you import this device.

Thanks very much.
