I don't know anything about Atmel Studio, but the ISP 3v3 pin is for powering the BlueSaab board/chip, and flashing the bootloader to the 328; that pin doesn't provide power "out".

You should verify that when the board is powered (regardless of method), that 3v3 pins have 3.3v, and go from there. Also verify you don't have any opens or shorts anywhere; solder balls are very small.

You can take (clear) pictures and upload them here so we can take a look.

It could also just be a setting with your burning method. Using Arduino software is pretty simple and easy.
