All block have disapeared app

I was working on an app for class on Tuesday and then i came on on Friday and the blocks were gone.



Tuesday, was that December 23rd?      Your blocks might not be gone, only hidden.  Please try this:   On the Blocks screen, right click on any white area.  A pop up menu will appear, select  Align Blocks Horizontally    or Align Blocks Vertically.   Sometimes, doing this will make 'hidden' blocks disappear.

If that does not work; self recover using the aia file you should have been saving to your desktop.

If that does not work, please do the following:  Tell us the name of your Project.   It may be needed to recover your blocks.   Also, tell us what you were doing on your project just before you ended the last session.  Were you loading large images, sound files or layouts or doing something else.   

Be aware, it is not always possible to recover blocks.  To have a chance at recovery, we need to know the name of your Project.  Also, this is the Christmas holidays so it might not be possible to do any recovery until after 28 December or later.
