Yes you got it. All the differences of binary made by 2.10 seems to be jmp -> jmps that saved some bytes and shifted the entire code. I chcecked the binary in BOSH and it WORKS. I wrote in a mistake the version that chinese guy used - 2.09.07 compiled on Mar 14 2011. I suggested him to upgrade on 2.10. Hope it will solve the problem.
