From FM 12, I am only being given the option to save as mif12 or mif7.
Unfortunately, SDL Trados only supports MIF files from versions 8 to 11. So mif12 throws an error that the FM version used to create is too new, and mif7 throws an error that the FM version is too old.
I've already tried "tricking" trados by editing the header of the MIF file manually to show version 9 point something, but it doesn't make any difference.
How can I get around this?
