...presentation!! How do I get it back?? Hey, I just accidentally saved over my school project with a blank presentation!! I need to get the actual pesentation back... Is it possible?? is there some recover overwritten powerpoints software i can donload???

Thanks in advance

Right click the overwritten presentation and choose Properties. Select the previous version tab and click the restore button.

I found this one also...
Click the Microsoft Office Button, click Server, and then click View Version History.
In the Versions saved for file name dialog box, click the previous version that you want to restore, and then click Restore.

microsoft 2007? (I don't have it but maybe if you did it might help.) Otherwise, then there's no way
