Trouble making new components

I've made a couple new components in the txt file as well as images in the proper places. they work in the sim and i've been balancing them there, however i'd like to be able to use them. Whenever i try to build a ship it says i do not have the tech levels required to build the ship. What could i be missing? I know i have the levels to build the components because i set their prereqs to be pojectile weapons lvl 1. also, in the research window, whenever i rollover a tech it shows completely non related technologies. However, when i research the tech, i get the proper components. Example: when i put my mouse over missile weapons, it shows a picture of a small meson blaster up at the top, but when i research the next level in that tech, i get the new missile weapon like i was supposed to.

thanks for your help,
Jaxem
