how to delete gosh application

Hello, I am using hanatrial.ondemand.com for some development.

Starting last I Friday, I started to have troubles. I am not able to start my application from cockpit neither eclipse.

In the cockpit, I can see my java application, but the state is "Could not read status of application healthcare: Internal Server Error (500)"

If I try to start another application, I have an error saying that I already have one application running.

If I try to delete the application, I have an error: "Could not delete application healthcare: OK (580)"

So what can I do ?

Thanks

Philippe
