After you export the file to a bcm file type (which is just xml), you
might need to set the version number from "3,0" to "3.0". I don't have
Danish installed, but from memory it produces the European
punctuation, which will make the English version unhappy.

Moving between locales can be difficult at the sql level, with
collation orders and such. We are aware of the pain. If you have
additional suggestions along these lines, I'd be happy to hear them.

Thanks,
