not sure if its your end or CB's but the singularity compressor and the centrifuge extractor aren't showing up in NEI. Nor do they appear in standard creative mode. I used the search function and browsed the tabs. (I could have missed it in the tabs through.)
current CC 64
NEI 1.4.0.4
ic2 1.107.35
4.2 advance machinces
Edit: I can make them but this is just letting you know.
