Navcore 9.xxxxx on Tomtom One 2nd edition

I tryed to update my One 2nd edition to navcore 9.xxx and also install a map. So far everything works fine, but when I try to plan a route. The touchscreen doesn't work... Can anyone solve this problem? Thnx in advance!
ttgo.bif:
DeviceName=TomTom ONE
DeviceVersionHW=ONE (v4)
DeviceSerialNumber=Z1xxxxxxxxxx
BootLoaderVersion=55136
ApplicationVersionVersionNumber=9510
ApplicationVersion=1234792.2
CurrentMap=Europe_Central_965_7250
CurrentMapVersion=965.7250

These things can happen sometimes when upgrading to an unofficial navcore

Personally I'd restore the backup just to make sure everything's back to normal, then try a different version of the same navcore

Europe Central is a ZONE map.
You might want to try a free standing Central Europe map, if you have enuf storage for it.
Central Europe 965.7250
