When exporting DO to USB and only the default language is copied (here: German; without "all languages" and "English" in the options), DO doesn't run and prompts an error "missing english language" when started from USB-Drive.
Copying engl. language to USB fixes this.
Thanks. I've raised a bug report with the details.
This is fixed in Opus 9.0.0.1:[ul][li]...[/li]
[li] USB/U3 exports in languages other than English now work even if english.dll was not exported[/li]
