Cross not recognizing turntables?

My eagerly awaited Cross Pack arrived today but I've been unable to get it working.
I'm running an external 3 channel mixer + two stanton T62s - connected & set up the exact way it specifies in the user manual & online guides, but it seems that my turntables aren't being recognized. For example, when I have the software open and try to calibrate the tables I just get a message saying "No input signal - please check the deck is connected and playing then try again"
Cross recognizes the u46 like it should but when it comes to the turntables it doesn't seem to know there are any connected. Could it be a problem with my mixer? I hope not as I just bought this thing ^^
not sure what to do about this, any advice for me?
thanks
