Acces a game through a .bat and a 3rd party program

I need a programmer that helps me to acces a game through a .bat and a 3rd party program. I got a .bat that acces the [login to view URL] from this game, and with the help of this .bat I got custom skins on this game. The game updates online itsfel once every run, so it replaces any modified files (and the skins also), so with the help of the .bat, the game SKIPS the updating part. I also have a 3rd party program that acces the [login to view URL] from this game, and works somehow like a trainer. Unfortunately, i don't know how exactly it works (the mechanics behind it, like i mentioned on the .bat starter) The [login to view URL] and [login to view URL] from the game are correlated (i can open the game from any of those, but i don't know which of them is the main starter). So the problem is I can't have the custom skins+trainer wroking in the same time. P.S. The game is written in Java, so a Java programmer would have priority.
