Question about Vmax VX2 Pro LT-B

Good day We recently purchased a vmax vx2 pro from you. Unfortunately, we have discovered that it only travels at 20 km/h. Obviously Switzerland and Austria have different legislation, which we were not aware of. We (a couple of friends and I) bought it together as a wedding present for a mutual friend who lives in Austria. The scooter is also going there, which is why we want to load the Austrian software onto it. Can you please help us and provide a link for the correct software? Thanks in advance and best regards Oliver Huser & friends
