Lpc2000

Hello All, 

   Finally I got my olimex prototype lpc2138, and try it for the
first time.
   I plug Power supply, DB9 to pc and launch Philips Flash utility to 
read device ID, after button reset as instructed raise a 
message   "Cannot communicate with test board" then
   I have no idea where`s the problem. 
   FYI, I have 6 feet cable DB9 1 to 1.

Any Idea how to solve it?

Sorry for my english.

Thanks
