MX Simulator

I downloaded it and put it in my folder for mx simulator when i go to play online it says its too old.

create a short cut of it and delete the previous shortcut and the old snapshot its self

did you actually open the game with the new snapshot? sounds to me like you opened the game with the old one.

Put the new snapshot on your desktop
Rename it to mx.exe
Replace the old snapshot with the new one it should be in 'program files (x86), mx simulator' or something.
