Your code looks like it leaks memory. Why are you using strdup?

const size_t limit = 2;
unsigned* MapTextures = new unsigned[limit];

for ( unsigned i = 0; i < limit; ++i ) {
   string Cmd;
   LevelStream >> Cmd;
   MapTextures[i] = LoadTextureWithAlpha(Cmd.c_str());
}

When you say it will only load one texture, do you mean that both
MapTextures elements contain the same value?
