Sorry about that. Here's the link: viewtopic.php?f=31&t=27245
Also, I'm using an Uno, not a Mega.
Software SPI works on the Uno too. If you can't use the hardware SPI pins, software SPI allows you to re-map it to other pins.
In the case of the Logger shield, there is one more issue: The SPI MISO signal is hard-wired to pin 12. You will need to cut either the pin or the trace and add a jumper to the pin you will be mapping it to.
