multitrack training on CQ20B

Hi,

May be a stupid question: I want to train to mix on free multitracks recording (The 'Mixing Secrets' Free Multitrack Download Library). I created a directory named CQ-MT002 (I have already a CQ-MT001 directory) on my PC under AHCQ/USBMTK. I copied the training WAV tracks in the new directory.

I plug the SDHC card in the CQ20B slot. Under SYSTEM/STORAGE the SD Status is OK. But when I want to select track to test it under SYSTEM/RECORD the CQ-MT002 directory is not seen. What do I do wrong ?

Many thanks,
