Serial Key doesn't work

[yenmeng]

I recently downloaded a game w/ crack: here. When I open it though it comes with the serial key with 20 characters, which doesn't seem to fit the 16 character license code for the game (startup.exe).

Am I just stupid or is there something I need to do here?

Download from here, already cracked & works:
Mega.nz or Terabox
