The minidump was too big via the error dialog, but I did send the zip files without the dump. I can try to send the dump if you think it will help. I was attempting to open the VST Editor for Ivory II (American Concert D). Today was the first time this has happened, but it is happening every time. I was in that same editor as recently as about 2 weeks ago.
EDIT: Build 3540 (x64)
EDIT 2: Turning off the Enable High-Resolution for Cantabile Windows" option gets around this issue.
