Thats exactly what happened to me --0GB installed. I emailed them and they said this occasionally happens. I told them what I had, and they listed all the recommends. Is your make and model listed ? Anyway I was very pleased with the service and the product and it made a huge difference on my Acer notebook going from 1 to 2 gb running Vista. I fitted two cards of 1Gb each so as to keep the dual channel function.
To upgrade then, you need to remove the two 512MB modules and replace with two 1 GB modules.
Yes Crucial is a good company to buy from, you get a good product and a good guarantee. There are, of course, other good products. When I built systems I always preferred Kingston RAM over others, as I never had a faulty or failed in the field module.
Yes - you should preferably buy 533MHz modules (PC2 2400), as these are the best match for your motherboard. Buying faster RAM is pointless, and just might cause intermittent problems (depends a lot on the specific motherboard design and chipset).
You can sell you old modules, or keep them for emergencies.
