Blink LED example does not work
It looks to me like you've got the Cathode of the LED wired to Vdd. That's the wrong way round, so you should turn around the LED. Or alternatively, wire the Cathode to GND instead of VDD. Also, it's poor practice not to include a resistor in the LED current path; 220 Ohms or so should be fine.

UPDATE:

It looks like you've got more problems than just that. Going by the pin-out posted by 'TMa', your Vcc,GND (p7,p8) look reversed. Also the GND on pin22 is unconnected. Usually all GNDs on an IC should be connected because they are internally connected via the substrate.
