citymapper crashing up on startup

hi guys,



I'm in real trouble here. I live in london and I use this citymapper on a daily basis more than I use whatsapp lol... now I'm at a loss because it closes on start up. I did update it to the latest version and that's when it started.



my solution is possibly having someone with a note 4 and 4.4.4 make a backup with titatnium and uplaoding it for me, so I can install the latest version from google play then wipe and restore data from your working update. would that be a solution? I've done something similar with whatsapp+ which is how I thought of it.



I've been in contact with citymapper but to be completely honest they are just like, is your phone rooted, what version etc etc. I asked them to do the above but no reply yet... and I doubt I'll get one...



is someone able to help me out or possible tell me how to resolve my problem?



here is the app I'm talking about

on a side note I'm really trying not to re-install or wipe everything, it's a real task to bring my phone back to my liking's.

thanks in advance
