"Kickback" SRB wont load...after breaking something in the files...

[The Kidd]

I was playing around with the save file trying to hit the Mun with a simple SRB with a probe on top. But, when i finaly realized that Thrust per percentage or whatever changed the fuel comsumtion too. so i went to the actual engine in the squad folder and edited it so it had more thrust, less fuel being used. but when i tried to get to the file that i needed to edit, it had to be open with something else (acording to youtube) but i messed that up and made all the files i was trying to edit open with notepad then messed with the thrust. but now my 2nd favorite engine is gone. :-(

If Steam, verify the cache. If not, reinstall and copy your save files.
