[SOLVED] Only one CDJ responds in Traktor Pro 2.6! Even when both CDJ's are connected the same!

Hi everyone, I recently got a new laptop so I'm trying to set up my 350's and link them to Traktor pro 2.6 again. The problem is that only one CDJ responds. I have done everything I did on my old laptop such as download the drivers and traktor mapping however one just doesn't respond at all.. but the other works perfectly. Has anyone else had this problem?
