Most likely, you installed Tribes of the East 3.0, so you need to enter the same commands, but in different files.
D:\My Documents\My Games\Heroes of Might and Magic V — Tribes of the East\Profiles\EM\input_a2.cfg
and
D:\Games\Heroes of Might and Magic V\Heroes of Might and Magic V - Tribes of the East\profiles\autoexec_a2.cfg.
Accordingly, you have different paths to these files. This is just an example.
If it's Heroes of Might and Magic V, you change and add to the files: input_a and autoexec_a.
If it's Hammers of Fate, then input_a1 and autoexec_a1.
If it's Tribes of the East, then input_a2 and autoexec_a2.
I entered the commands, and... in the game, the keyboard and mouse completely stopped working. More precisely, everything works in the main menu, but as soon as you load a mission and the message "press any key" appears, everything stops responding. No matter what I press, there is no reaction. What could be causing this? P.S. I have Heroes of Might and Magic V Gold, damn it!
