ModLoader doesn't works since the client of MW2 that AlterIWNet release with version 1.3.37a build 10802-1 makes the client window name changes everytime it restarts not to mention its Runtime-Scantime meaning everytime you open the client the name will change, and if you try to change it while it still running, it still be the same name, because it has some coding which prevents renaming of the window, cuz the code "refreshes the window" to its original state, hope this helps on the problem.
