Make sure the mod 'ModuleManager' is of latest version and installed. Typically every mod resides in own directory.
Make sure to install all mods according to instructions. You put every mod directory next to 'Squad'. In Vanilla game, the Folder 'Squad' recides in GameData and these are official parts.
Mycen_keriadyne: Is anyone having the same issues? Make sure you install the mods in right folder: $KSP_Install_Dir / game / GameData / $Directory_Where_Mod_Recides.
