I have just purchased and loaded VectorWorks. I find that to run the program I must first provide the serial number. However, when I enter the long alphanumeric shown at the bottom of the sticker which is to be placed on the registration mail card, I get the message that the serial number format I've entered is incorrect. Where do I find the required serial number and what is its format? David Shoup (dshoup@whidbey.com)
