It won't start – Sketchbook® Review

Ive been trying to open and use this app for over an hour, complained on the official Autodesk forms and it will not open and start, all it does is show the logo, flash my current drawing and crash. Ive tried restarting my iPad but I'm too scared to uninstall it. But I love this app, I used it to draw everyday and complete the challenges/art games but now I cant, Autodesk get your stuff together!!
