James,

Can you please download Alice 2.3.5d version. If the error you are getting is the missing matrix4d class, this bug has been fixed in the latest release.

Thanks,
Aik Min Choong

Can you help with this? This would be a good place (the Alice educator’s list) where you might describe how to work with these files that become corrupted, if you think that is a good idea… Just a thought…

Later,
Don

I have a student project (Alice 2 world) that appears to have been corrupted. When I try to open the file, the Error dialog appears with the message "Unable to load world". The "more detail" includes a "NoSuchMethodException".

Is there a way to recover from this situation? I'm running OS X 10.8.5 with Alice 2.3.5. The student is running Windows with whatever version of Alice 2 was current in August.

I'm guessing something in the Alice world file is missing or corrupted. It seems like it should be possible to unzip the  .a2w file, remove the offending object, and rezip the file. Has anyone tried this? Is there a way to tell from the stack trace in Alice (or otherwise) what the offending object is?
