Registration

Many thanks to Philippe for decoding the registration process:

• Take your serial number (e.g. 8810)
• Perform the following calculation:

serial + (53/serial) + (113*serial/4)

• This is unlikely to be an exact number, you might have to round it (if not sure, try both!)
• Now convert this to hexadecimal
  • In google type in "... to hex" then drop the "0x"
• Finally, add -3BE to the end

For example with a serial of 8810

• 8810 + 53/8810 + 113*8810/4 = 257692.50601
• We round this up to 257693.
• 257693 to hex in google = 0x3EE9D
• So the final registration code is 3EE9D-3BE
