Arvard I'm not sure what you mean but I repacked and re-uploaded anyway.

You can unpack it yourself into a folder within the mod folder. The folder should have the name "Lafiel.Abh_mod".
=> Cosmoteer/Mods/Lafiel.Abh_mod/
Youd should see:
Cosmoteer/Mods/Lafiel.Abh_mod/mod.txt etc.
Edit: Cosmoteer/Mods/Lafiel.Abh_mod[WIP]/ should work, too, but above is safer.
Edit2: The following parts will be changed so don't save designs with them. You may not be able to load the designs again. Just use placeholder when you save your design.
big_antiproton 1 cannon
big_impulse_thruster
photon_torpedo_tube
big_antihydro_thruster
