Arduino Nano "programer not responding " on Win8

Hi,

I am using an Arduino Nano on Win7 64bit and when trying to upload a program I get about 10 errors that say “programer not responding”.

Things that were suggested online that i already tried:

-Installing the latest FTDI Usb driver

-Pressing the reset button before and/or during the upload

-Making sure i have chosen the correct board in the IDE

-Trying different USB Cables / Ports

Can somone tell me what to do?
