Chris, have you tried a full reboot? Press and hold the power/sleep button until it says "slide to power off" Then slide your finger to fully power down the phone.

Wait 30 seconds or so and then turn your phone back on by pressing and holding the power button for a few seconds.

If that does not resolve your problem, make sure you are connected to the internet via either 3G or WiFi and that those functions are enabled in the settings menu. Also, make sure you are not in airplane mode.

try to on your phone and off it the wait for 30 seconds then on it after you on it go to settings and turn your location services and wifi on then after go apps store the go to the update section then press update all there you have it problem solve
