I have Alice 2.2 and I can not change my preferences either. I try to change it and then I restart and nothing saved. It keeps resetting everything to default

I tried putting Alice in many different folders from the desktop to C drive, to program files, etc

I tried putting the "AlicePreferences-COPY" in the Alice2 folder in my documents and settings and it did not do anything. I got the error

Alice version: 2.2 08/05/2011

So I removed the -COPY from the file name so it was "AlicePreferences" and it gave me an error when i loaded Alice.

I need to use Alice in Java mode for Computer Sci 120
everything in class is explained in Java and to work on the assignments in Alice format is confusing because a lot of the stuff is worded differently in Alice mode.

Please Help
