I recently bought the Arduino Uno and two extra ATmega328's (w/ the Arduino bootloader) from sparkfun. Everything has worked great so far, but when I removed the original ATmega328, and tried replacing it with the either of the ones I bought from sparkfun, I couldn't upload sketches to them.

The LED blinks when I reset so it seems to me like the bootloader is on there, and when I try to upload it does the reset and I see one blip on the RX, and then it tries again, and nothing.
Any help would be appreciated,
