Rekordbox and Audacity

So I'm using a DJM 2000 and 2x CDJ 2000,im trying to record using audacity and the rekordbox performance software. Basically the problem I have is I can either have both CDJ's playing through the same channel by using the cdj audio driver, or i can have the ASIO DJM Driver (im on windows so i used ASIO4ALL), but this stops me from being able to record with audacity as it sais the sample size/project rate is incorrect. However as soon as i close rekordbox performance software I can record with audacity again, so its definately to do with the software.

Any suggestions?

P.S Merry Christmas
