GWT compilation failed

I am developping a GWT Application and when I was about to compile I got a message "GWT Compilation Failed" without any stacktrace.

Then I've tried something even simpler, like creating the sample application and I've got "Creation of element failed. Reason: Invocation of com.google.gwt.user.tools.WebAppCreator failed".

I did a lot of research and tried a lot of stuff (change folder permissions, deactivate antivirus, changed version of eclipse and gwt, checked windows event logger (found nothing), recreate workspace, remove ClassPath environment variavble...). The most weird thing is that in my personal computer everything works fine, but copying the eclipse folder to my work's computer I get always the same problems.

This is the .log from eclipse.

Does anyone has any ideas about how to fix this?
