u may try with the lowres compatibility mode of the mod, as 64MB graphics ram doesnt seem to be sufficient to show the high res textures of the CF mod. u can trigger that mode when u activate the mod in FLMM (another clean install needed for that - sorry)...
sorry, but the card memory should be rather 256 than only 64. i doubt that lower screen resolution will help, as there still is the problem with the texture size not fitting into the card memory.
