a java exception has ocurred,
How can I solve that ?
depends - what exception and how did it occur?
I would guess you double-clicked on the JAR you downloaded of this week's update, thinking that's how you run the game. That would be the incorrect thought for you to take.
You should have read the yellow text in OP above where you clicked the download link:
Or skim through this page's posts
Or search for "java exception" in the thread and learn the following:
If you have a windows (or Mac or Linux) computer and you don't have TOA on your computer already, you should download the WIN (MAC/LINUX) package and unzip. Then, if you want to play a subsequent weekly or monthly update, download the Java JAR and move it into the WIN game folder to replace the old JAR in there.
