I just posted WED 1.5 release candidate 2. If you grabbed RC1 and hit the crash on export on Windows, please grab this ASAP and file a bug if your crash is not fixed. Of the four or five crash reports I received, two contained reproduction materials and both were the same bug – a crash when exporting a ramp position with no airliners, Windows only. This is now fixed.
Thanks for update!
Ben, where I can send X-Plane bug?
