it just check the files, and update it if necesary... it guess it also patch the memory to change the token (cuz engine.dll seems to be un-encrypted, i didn't looked at it, but the file size looks like the original) 
  
  
  
Reading the data with winhex, i got: 
  
- protocol is 530 
  
- token is 5B3B272E5D36363131313D3D2D252640215E2B5D 
  
  
  
For in-game walker just hex-edit the original token at engine.dll with this token... i guess it should be enoght. 
  
  
  
PS: i'm too lazy to make an account :P, but it should connect with this token, and a walker that use C3 (530) data (i tested with 10.5.3, so 10.4.9 should works too)
