Missing parts from mods?

[MaxwellsDemon]

Hello... newbie here. I have 1.04 on a Windows 7 system, and have installed MechJeb, Asteroid Day, and ScanSat (in that order).

MechJeb is working fine. But I do not see the parts for either Asteroid Day or ScanSat in the tech tree; do they become available at certain nodes? Or since I began my Science campaign before installing them, does that mean I'd need to restart the campaign with those mods already installed?

I don't think you necessarily need to restart the campaign - you should be able to go back to the updated tech tree and unlock the missing parts individually.

I don't see them show up in the tech tree, in either techs I've researched or ones I have yet to research-- other than the MechJeb parts, which do show up properly.

Update: I discovered my problem-- I had unzipped the other mods in GameData, just like I did for MechJeb, but the folder hierarchies in the ZIP files for the other mods were not consistent with MechJeb. Moved the files to the proper folders/levels and they work fine. Noob error.
