Arduino (genuine) micro not uploading [SOLVED]

Development Tools IDE 1.x

I have code that will compile, and even tried using the blink example frome Arduino IDE and each time I try to upload I get this:

Sketch uses 3972 bytes (13%) of program storage space. Maximum is 28672 bytes.
Global variables use 149 bytes (5%) of dynamic memory, leaving 2411 bytes for local variables. Maximum is 2560 bytes.

An error occurred while uploading the sketch

I know i'm on the correct port because I am able to retrieve board info. I also just updated my boards list with Arduino AVR boards version 1.8.2

any idea whats causing this/what I could do to correct?

Make sure the port isn't open in any other program.

Sometimes the port gets stuck open. Restarting your computer will resolve that issue.

that was easy
