can you please share your ninja2.a2w file so we can try to see what is wrong?

jac 03-29-2011 02:26 PM

added and i can confirm it was working perfectly fine the week before i retried to open it.

Based on what the little I know about error trying, catching, and throwing; something either happened between here:
[CODE]
at edu.cmu.cs.stage3.alice.authoringtool.Actions$2.actionPerformed(Actions.java:92)
at javax.swing.AbstractButton.fireActionPerformed(Unk nown Source)
[/CODE]

or here

[CODE]
at java.util.zip.ZipFile.<init>(Unknown Source)
at edu.cmu.cs.stage3.io.ZipFileTreeLoader.open(ZipFil eTreeLoader.java:66)
[/CODE]

or here
[CODE]
java.util.zip.ZipException: invalid CEN header (bad signature)
at java.util.zip.ZipFile.open(Native Method)
[/CODE]

What it means, I don't know. Sorry. :(

This problem is unfixable. You could try opening the project on different versions of alice but sorry, this is unfixable. This happened to me with a really big file. I know how it feels, but this stuff is common. Go to the earliest backup you can. But, whatever you added that was odd or was imported. Dont import it!
