Q: I lost my activation key and username!
A: Are you still using the same e-mail address? If you kept the receipt, you can find your key by searching for an e-mail from orders@bmtmicro.com. If you didn't save that message, you can send an e-mail to keys [at] bmtmicro [dot] com describing the situation and they should be able to retrieve your key.
