When connected to your computer put files like games and software that you want into the folder named OTHER. Hopefully then, when you turn your phone on and go to the folder named OTHER it should give you an option to install press yes and then choose to put the media in the application folder or games folder depending on what it is.


hope this helps

Try deleting the application from your phone, then re-installing it, but make sure its a format thats compatable with your phone.
