Someone please help. I really messed up my IMac. I was trying to follow some instructions on installing something, that required me to replace some .dylib files. all of them were replaced fine but one. I found the original file in the folder (libstdc++.6.0.9) and moved it to the trash. The i moved the replacement one into the folder. I immediately lost all items on the desktop and the finder and all apps closed. I tried to restart, and now it wont even get to the login screen. I'm completely stomped and could really use some help. Any ideas or solutions would be greatly appreciated.
