I really am new to programming 3D. I did a test run of XNA-Spacewar. 2D Was fine. 3D caused a DeBugger to say: "This Card Does not support MipMaps" Whats a MipMap? i think i need a newer card for it but still.

Wow, it must be a pretty old card! Are you sure it was a card and not a PS One? :-) Anyway, mipmaps are used to reduce aliasing of large textures. Read all about it here: http://en.wikipedia.org/wiki/Mipmap

I know of no pc 3d card which doesn't support mipmaps - even software renderers like the GDI generic one support them - which suggests theres something else going on.

Perhaps it's using non-power-of-two sized textures? I know that only recent cards support mipmaps for NPOT textures.

Run the code in the debugger and post back exactly which call is failing. Selecting the debug runtime and enabling unmanaged debugging will also give you more information.
