My ukits doesn't work

I'm an embedded software guy who want to learn how to play with NiosII. I bought Microtronix's ukits last month.

After read Microtronix's documents in the CD named "Microtronix Nios II Linux Distribution Quick start Guide" and "ukits quick start guide", I follow the instruction include compile kernel, compile filesystem, upload kernel, upload filesystem, program the chip with linux.sof... etc. Finally, when I type nois2-terminal in the shell, I got the following message:

[SOPC Builder]$ nios2-terminal

nios2-terminal: connected to hardware target using JTAG UART on cable

nios2-terminal: "ByteBlasterII [LPT1]", device 1, instance 0

nios2-terminal: Warning: The JTAG cable you are using is not supported for Nios

nios2-terminal: II systems. You may experience intermittent JTAG communication

nios2-terminal: failures with this cable. Please use a USB Blaster revision B

nios2-terminal: cable or another supported cable. Please refer to the file

nios2-terminal: errata.txt included in the Nios II development kit documents

nios2-terminal: directory for more information.

nios2-terminal: starting in terminal mode only (Control-C exits)

Any body knows what wrong on it ? Do I need a USB Blaster revision B cable ?

Thanks
