DJM 900 Nexus 2 driver

Every time I plug into a 900 nexus 2 it asks me to install the driver even though I have already. I end up justing hitting skip and it works fine. Is there a way to maybe un install and reinstall the driver so that it stops asking every time i plug into a 900 Nexus 2. This doesn't happen when I plug into a 900 nexus or my ddj sx2 its only with the 900 nexus 2
