WHAT HAPPENED??

I update and now it dont work at all!!! What gives? I have iphone4 and purchased this so I can check for stations while in my car. Had it a few short weeks and it was great. Then they offer a new and improved version!! Ok, i thought and downloaded. Now app starts up and shuts down right away every time! How do I get the old one back???
