How to solve the RUNTIME ERROR! Thread - Perisno mod for Mount & Blade: Warband

One of the most common crash errors that people stumble upon is the Runtime error. Most people think that this error is caused by the mod only - this is where people are wrong. It's a very common crash - I've had it myself plenty of times - and there's a few different solutions to the error. Though usually only one of them works. If none of them work, then you get to slap me.

A. You may have a cracked version of the game. Please buy the full game if you do.
B. Go and fiddle with the game launcher's settings (Tutorial below!)

1. Launch the game through Steam or wherever.

2. Click Configure to enter the settings.

3. Then head into the Video tab and either disable or enable Load Textures on Demand.
If you have it enabled by default, then disable it. If you have it disabled by default, then enable it.
For the majority of players, it works by enabling it.

4. Head into the Advanced tab and enable or disable Force Single Threading.
If you have it enabled by default, then disable it. If you have it disabled by default, then enable it.

That should just about be the most common ways to fix the Runtime error.
I enabled both Load Textures on Demand and Force Single Threading when I had the Runtime error, and it fixed it.
