When I was registering my new cool Bamboo Pen, I couldn't get the software key working. I mailed all my info to support, the guy said that the key is fine and asked me to check whenever I had the right model selected. I wrote that it was fine and the key wasn't working even thought I tried replacing W with VV, etc. So, that support guy asked me to check it again, but this time he specified to look at the model number. He was right, I selected the older model instead of "Bamboo 3. Gen. Pen".

That was deeply embarrassing. I can't get myself to draw anything due to the stress.
