When I import an old Beyond file on my Mac G5 (running Metro 6.3.8.3), there's no problem. When I try to import the same file on my MacBook (running Metro 6.3.8.5), I get a message "This data file is too old. Try using the old version to export, then import."
Is this caused by the difference in processors (G5/Intel) or by the difference in version (6.3.8.3/6.3.8.5)?
