Do you have a plane to stop it from falling? Maybe post a picture. Just starte the GE then press the print screen button on you keyboard, if you have one.

Then paste into a graphics program and save it, and upload it here with the advanced manage attachments.

Not my problem anymore:D
I have new one.
