My Internet us working fine I'm using my phone to communicate with you all of my other apps work fine

Hi I am still having problems with the app I connected to wifi but and the app opens the timer spins constantly but YouTube won't open. When I press download list I can't access it the app keeps freezing will I delete and then re download the app. Thank you for your help.

I forgot to say I am using the iPhone 4S on the 3G network meteor Ireland all of my other apps are running fine this one just opens then crashes without loading any suggestions and when I tap the search or list button nothing happens.
