Alice Crash: Index (PLEASE HELP!!!)

[Toothpaste35]

I tried loading my world the other day and this error appeared and know I can't open the file anywhere:

Unable to load world


Alice version: 2.2 08/05/2011

Throwable that caused the error:
edu.cmu.cs.stage3.alice.core.IllegalNameValueExcep tion: Unfortunately, something else in this world is already named "index," so you can't use that name here.
