I know you're working out the bugs. Here's some info:
Moved to iLok version. Metframes load fine, but getting "invalid" error when trying to load channel sets into a new frame on Windows 10 / VEP 7.1.1263
Also, copying/pasting a group of channels from one frame into a new frame causes VEP to crash/shut down.
Uninstalled .1263 and rolled back to .1245 - now I don't get the "invalid" error, but VEP immediately cashes/shuts down.
Uninstalled .1245 and rolled back to .1120. All the frames and channel strips I created in this version and prior are working fine.
