texture 1+ doesnt work in shader

i can only get GL_TEXTURE0 to be sent to shader and idont understand why the others doesnt work..
EDIT:: Chagned the code for easier read...
in this code altought i should get texture2 (GL_TEXTURE1) i get tex1 (GL_TEXTURE0)

given that, according to that code, you don't bind any texture to texture unit 0 i'm impressed you are getting anything at all...
glActiveTexture(GL_TEXTURE0);
glActiveTexture(GL_TEXTURE1);
glEnable( GL_TEXTURE_2D );
Textures[0].LoadData("../Data/Textures/sand.tga");
Textures[0].CreateTexture(GL_LINEAR,GL_LINEAR_MIPMAP_LINEAR,2.0f);
Why are you doing glActiveTexture for texture0 then immediately changing to texture1?
glActiveTexture(GL_TEXTURE1);
glEnable( GL_TEXTURE_2D );
Textures[0].LoadData("../Data/Textures/sand.tga");
Textures[0].CreateTexture(GL_LINEAR,GL_LINEAR_MIPMAP_LINEAR,2.0f);

seriously nobody got any idea? ive tried everything i could think of... ive set only GL_TEXTURE1 and 2 but then i get no texture at all.. ive been working with this for hours without finding the problem.. its frustrating..
if i use texture2D(tex2, gl_TexCoord[1].st) when TEXTURE0 is enable i get TEXTURE0 when i dont have TEXTURE0 mnebaled and only TEXTURE1.. i get nothing.. just black

there is something seriously wrong here.. ive tried removing some of the code.. and this is just wierd...
with jsut these to lines i get the texture0 rendered
glGenTextures(1, &iTempID);
gluBuild2DMipmaps( GL_TEXTURE_2D, GL_COMPRESSED_RGB, m_uiWidth, m_uiHeight, GL_RGB, GL_UNSIGNED_BYTE, GetData( ) );
i dont have to active any GL_TEXTURe or enable 2d_TEXTURE i dont even need to bind the fricking texture all i have to do is Gen and build it.. and its rendered... ?!?!?!

I remember if using shaders you don't need to actually enable GL_TEXTURE_2D, that might be the reason it's working that way
Have you tried
[SOURCE] Textures[0].LoadData("../Data/Textures/sand.tga"); Textures[0].CreateTexture(GL_LINEAR,GL_LINEAR_MIPMAP_LINEAR,2.0f); Textures[1].LoadData("../Data/Textures/grass.tga"); Textures[1].CreateTexture(GL_LINEAR,GL_LINEAR_MIPMAP_LINEAR,2.0f); glActiveTexture(GL_TEXTURE0); glEnable( GL_TEXTURE_2D ); // Bind texture 0 ShaderProgram->SendUniform("tex1", 0); glActiveTexture(GL_TEXTURE1); glEnable( GL_TEXTURE_2D ); // Bind texture 1 ShaderProgram->SendUniform("tex2", 1);[/SOURCE]

ok this is what ive got
still its "tex1" thats being rendered and not "tex2"...
