Please fix – iSkate - GPS skating computer for inline and roller skates Review

Ok, I liked the app a lot until you came out with version 5.0. Now the app doesn't open even after rebooting my phone. Sorry about leaving a poor review but I can't find a way to send an email letting you know it's broken.
