Yep, i'm very sorry about it. Version 2.57 is actually broken.I bought this yesterday for my CC3 and it looks great after a quick play with it.
One issue so far though - I'm in the UK so downloaded the UK logo pack OK from within the app, but the extraction seemed to go on forever and not complete. In the end I copied the file to my USB stick and unzipped them on my PC, but was I just impatient? It must have been going to 10 minutes or so, as it was long enough to trigger the car going into power shutoff mode, is that usual? It's a shame there's no logo auto-assignment for the UK as it's a bit of a pain manually doing it.
there is a problem with Logo extraction and Dutch language.
they will be fixed tonight/tomorrow with v2.58.
