Query: Flash Trax XT memory card reader

I just got my Flash Trax XT today and was shocked to discover that it won't read Sony Memory Sticks. I tried to see if they have an adapter so that the reader will read my memory sticks but none is available. I can't understand why it does not support one of the most widely used memory cards in the world. Or at the very least have and adapter at a reasonable price that I can buy. Why was the fact that memory sticks don't work in this device not made clear in the buying information. The player looks like it is a very nice unit but I'll never know..........
