All of a sudden my apps on my sd are not loading, you see them on the screen (not in the app drawer ) with the default android logo and when you click it, it wont run. The memory card works as you can see stuff stored on it with a file manager etc. Also I can see the list of apps on the sd when i go on manage application and i can also uninstall if i want. Ive tried rebooting multiple times to no avail, also turned off phone and removed and re entered sd card twice but still didnt work when i booted. Anyway to solve this.
