don't be disappointed. Ican understand why you are angry.

Compared to those guys who have be blocked in BEC for a few years, you are really really very lucky, becaue most of your PDs are just after 2006/01/01, right? Meanwhile, whenever your PD is current, you have to spend lots of time and Money on it. Although you feel cheated this time, you have finished your I-485 forms and you can be ready to file your case once it is current again. So, don't be disappointed anymore. Just be patient.
