I have the Software for 5 days on 2 mk4 systems and i didn't have any trouble. Just one hangup while boot process, but I start the car 5-10 times daily. With elder SW-versions it hung up 1-2 times in the year, too. Im very happy with that software yesterday I installed the SW again with standard boot-logo and version-text.

P.S. if the info- and sel- button doesn't work, aux-fan or BMW-ASSIST, you have to go to BMW-Dealer to encode the mk4. This installation deletes all car-specific settings (older radio, vin, model) and the mk4 is set back to factory mode. these problems are no issues of that software version.
