No longer opens

Used the first version ALL the time (would have given it a strong 4 stars). . I was excited for the update but now it wont even open. Please help figure out this problem. 5$ is an expensive app to just look pretty on the home screen!!!!

UPDATE
Seems the same company is marketing a new app that has the same features. Wish they would fix the original rather than making of inoperable!!!!!!!! Scam
