Major problems

Wont install and wont delete, it just says installing but does nothing, apple says to contact the creators and the creators tell me to go call apple..!! please fix this app. I paid to use it not to look at an icon I cant delete or use at all, I would warn you against doing the update if you like using the app. I bought this app at full price day one and now all I have is a dead icon I cant get rid of and some runaround from everyone included. Im a little upset.
