We use a crystal on the board not a resistor capacitor, maybe that's the problem.
I don't think it will oscillate if you set it for external RC then use a xtal. Never tried it, but I think that may be your problem. No oscillator means it will take a long time to do anything.......
I have an oscilloscope and one of the first things I always check when powering up a uC board for the first time is that the oscillator is running.

Its been a while since I used the Atmel set up as I have been playing with PICs for a while. And my PonyProg has a home made interface, but it did all go together quite easily.
Sometimes I sits and thinks and sometimes I just sits.
