Are you sure you have a complete "openLC North America" installed?
Your FTXCentral is still showing "openLC NA Alaska/Canada" (only).
Yes, it's possible to run " UTX Canada Version 2" with Orbx openLC. It does similar the same as "Orbx Vector". (Vetor is worldwide, UTX Canada is of course Canada only)
UTX and Vector don't have any influence on full fat Orbx regions like NRM, SAK a.s.o. These sceneries already have all necessary mesh, landclasses, objects installed.
You'll find endless fruitless discussions in the web about comparing Vector and UTX (what is better, what is more exact?), this is still the user's own personal feeling.
