I need help, again

This is what ive got at the moment. The computer is not uploading programs to my arduino uno, while it did it about 5 mins ago and ive only changed some code. here is the error message:

Arduino: 1.6.12 (Windows 7), Board: "Arduino/Genuino Uno"

Sketch uses 2,308 bytes (7%) of program storage space. Maximum is 32,256 bytes.
Global variables use 53 bytes (2%) of dynamic memory, leaving 1,995 bytes for local variables. Maximum is 2,048 bytes.
An error occurred while uploading the sketch

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

Im in distress, please help me.

Switch on VERBOSE and post the actual errors from the console window.

Use code tags to do so ( </> )

Disconnect everything from the board also and try again.
