Hi Rola,
Thanks for reporting this, and sorry you've had that happen.
Unfortunatly if you're experiencing a crash on startup, the only thing I can suggest is you either wipe the Rockfax application data or reinstall the app.
I'm on holiday from tomorrow but when I'm back next week I can inspect what may have caused this. It could be a certain route you have wishlisted that is causing this or it could be a large bug with that feature.
In the meantime the best option would be to leave the sorting option as default and try using the UKC wishlist page to order your wishlist. It's not ideal but it should provide a stop gap until I can look at this.
Regards,
Martin
