Not able to move anymore... ;(

[xSauriaNx]

So yeah, was playing ATTD again out of nostalgia and hearing the news for the brand new hard mode but now, every time I load the game, Daniel just stopped moving and won't move at all while I am pressing the WASD keys for movement.

I can still look around with my mouse and probably interact with any object if there's anything I can interact with nearby.

Here was some of the stuff that I did before consulting here:

   
• Reinstall = Still the same problem appearing whenever I'm in the game.
     
  
• Keymapping = I can do it by putting all keys near the Arrow Keys but it feels awkward to play that way... it ain't CS 1.6 anymore. Not to mention, harder to press for my fingers. (One thing to note is that when I bind them on WASD, it just shows up as "None")
     
  
• Searched the net for some answers = all post were related to controllers which I don't use.
  

Spoiler below!

so if there's someone asking for my spec it's an old acer travelmate TM4750Z in Linux Lite
it runs well windowed...
