Error installing the RetroArch Emulator on my iPhone 4S?

I go to the CoolROM website and navigate to the non-jailbroken iOS download and I tap it. It appears in my home screen and says "Waiting.." I wait until it gets about 3/4 of the way through and it says "Installing.."
I know I have to change the time to 2012, so I then change the date in my phone back to some time in 2012. After a while an error message pops up and says:
Could not be downloaded at this time"
and it gives me the option to retry. Any ideas as to what is going wrong?

I believe that their developer license has expired, so the apps will not install no matter what.
