View Full Version : Alice will not open Project! Help!

10-24-2012, 01:33 PM
I've been working for many long hours on this for my school project, and now all of a sudden it wont open! My back up files do, but my latest file is so far back that it would take at least a week to get back to where I ended up.

Heres what the error says:

Unable to load world: U:\Project Attempt 2.a2w

Alice version: 2.3

os.arch: x86
java.vm.name: Java HotSpot(TM) Client VM
java.vm.version: 20.0-b11
user.dir: C:\Program Files (x86)\Alice\Required

Throwable that caused the error:

If you can somehow miraculously fix this problem I will be super happy, thankyou for your time!
