Sorry tigrik69,
The latest software version we have is the 4.01

It’s doubtful that lowenstein would make this available to the end user. Try checking with some of the suppliers in your area to see if they would offer a later software version.

its gonna take way more time then 1h to get an answer, they're a big company so id assume atleast 72h before any kind of response is made.
