hey i figured it out and got my 1.7.3 back! thanks a million Pangamma! theres just one last thing though. now that its on, on the screen in pink letters it says this
"Zmod: error detected - one or more mods affected
First error: failed to load configuration from config.txt
Log: C:\Users\(Name)\AppData\Roaming\.minecraft\mods\zombe\log.txt"
What is this and how can i make it go away?
