Can't access the app – MyNetDiary GPS Tracker - Running, Walking, Cycling for Weight Loss Review

I'd love to try this app, since I really enjoy the MyNetDiary Pro app and would like to sync them, but I can't access it. I downloaded it but it keeps telling me there's an error with my username or password, when I've verified these 100% on the other app and on the online version. I changed my password to make sure, and waited overnight to sign in to this app again (after multiple failed attempts), but still nothing. Please fix!
