for(int y = 0; y <= 100; ++y) ^ |Dereferencing Problem
Just to clean up your texture lookup a little bit (sorry I can't help with your problem):
GLuint TextureManager::GetTexture(char TextureID)
{
if ('0' > TextureID || '9'
GLuint TextureManager::GetTexture(char TextureID)
{
if ('0' > TextureID || '9'
this doesn't answer but just a suggestion to your GetTexture function:
GLuint TextureManager::GetTexture(char TextureID){ int textureNumID = TextureID - '0'; if (textureNumID >= 0 && textureNumID < 10) { return TerrainTextures[textureNumID]; } else { MessageBox(NULL, "That's not a valid texture", "RPG", MB_ICONEXCLAMATION); return NULL; }}

Okay, it no longer sends an error at me, but the window does come up and disappear. And the debugger still gives me that error message. I fixed the array though.
[edit]
When the debugger error message comes, this line pops up.
MapArray[yIndex][xIndex].ID = MapFileLines[yIndex][xIndex];
Another thing it does, is if I get the debugger to run without having it do the above, it says the error, when I get to the line where I declare my Renderer.
Heres my WinMain.

I don't know if you changed it yet but
for every loop that you have. the reason being is that you are declaring 100 elements and the index starts with 0 not 1. so you go from 0 - 99, which, if you count it correctly, is 100 elements.
edit: also when you are returning functions, especially with the files, you should accompany them with a MessageBox so you know which function failed. easier to debug that way also.

This looks kind of dangerous:
std::string MapFileLines[100];
Are you sure that every std::string inside MapFileLines is 100-characters long?
std::string MapFileLines[100];
