Crashes and loses video

[kortneyg31707339]

This is now the second time this has happened.  The program (not my computer) freezes up and no matter how long I wait or what I do nothing frees it up.  after exiting the program and trying to reload the video it says unknown error.  I just lost one that I spent hours on and had a deadline that I will not meet now since im starting over from the begining.  Customer service is useless and refuses to help.  how can I recover my video?

Premiere Elements automatically makes backup copies of your project in a folder with your project itself.  If I remember, the default is a series of 5 recorded 15 minutes apart.
