Hi.

I got a problem with starting up my game.
The vanilla game works fine but after I installed some mods on it, I get this error message and
the game doesn't start up at all.

I did install the mods recommended by the mode guide exactly the way it told me to and
yet here I am.

If there's any questions you have, please ask away.

Thanks.

"No valid video modes supported" usually means the widescreen mod was set to a resolution your hardware (or the mod itself) doesn't properly support. Try reinstalling the game and the mods again and pick a different resolution when configuring it.
