The hardest direction to follow with this file is that you don't have to extract it before it's renamed then put in the cache folder as described above. Sort of like I get into the habit of taking the packaging off my disk before I put it in the computer or take the microwave popcorn out of the plastic bag before putting it in the microwave to pop. Also beware there is an outdated youtube video out there that recommends copying the jar file from minecraft file 1.3.1 and putting it directly into the tekkit bin's file. This is the addy of said file The video here does NOT provide a useful solution to the current launcher problem. Thank you Jorcer & all for the advice. With out all if it I wouldn't have caught my mistake and would still be trying to figure out where I went wrong. Hopefully the feedback I give will prevent similiar errors.
