I recently purchased a fresh copy of Star Wars: Republic Commando (a long-time favourite of mine).

However, I have one major issue:

For the first two days I had no issues playing the game as usual. From the third day onwards, I was unable to move the player character. All keys are working except for: W, A, S, D (which I have set for movement).

I have tried restoring all settings to default, and also doing a complete uninstall and reinstall of the game.

Still not working.

Help. Please.
