Here is the error in question, which I recieve after attempting to open the world:
Code:
Unable to load world
Alice version: 2.2 09/10/2010
Throwable that caused the error:
edu.cmu.cs.stage3.alice.core.IllegalNameValueException: Unfortunately, something else in this world is already named "index," so you can't use that name here.

The world is fairly simple and seemed to have saved without error the last time I opened it. The world file is attatched to this post. Any ideas as to why this is happening or what I could do to fix this? Thanks in advance for any help.
