That`s for old version ET2009A.This key I made.Version 2009C is whit different protection.

et2009c definitely uses two new techniques:
1) it obfuscates the code - the code that you see in license dialog is not a pure CrypKey license code, but a transformed one
You have to RE the file and find it yourself. once you find the alog , you have make a revertive algorithm
It is possible
2) master/user keys of Cryp prot system are also hidden! guys from Canada started to be smarter, good step! they are encrypting/decrypting the key in runtime, so wont see anymore an eatable plaintext keys......

:)
good luck

a) read the info from good key using ckInfo, eg:
ckInfo113.exe /sitekey YOur_key_here

b) have you found the user/master keys from the et2010 SW?

c) it looks like the sitecode is obfuscated (intentionally damaged, but still OK in terms of ET SW), look:

ckInfo113.exe /sitecode 4FC3 C3C6 B803 034A E570 308D
CrypKey Copy Protection Information v1.13

Error #03: Error occurred parsing the Site Code - Check Code Length
