Dear sirs,
updating from v4.0.0.1535 to v4.0.0.1540 breaks german umlauts (ä,ö,ü) for SFTP drives. It is now impossible to change to certain directories, downloading is also impossible. ([R] Unable to change directory...)

Downdating is possible and resolves the bug.
Best Regards and sorry for the inconvenience!
