[flexcoders] Flex 3 trial version says it expaired

[hworke]

  Hi I just downloaded flex 3 professional trial version
  but as I was trying to start it, I got a "trial expired"
  message. I still have flex 3 beta 2 installed installed
  in my system; am I getting this because if this version? 
  Did any one else also had this problem?

  Thanks...
