error importing

So today I was working on a project that consisted on an mp3 file and a few recordings. Finally I wanted to do something else so I saved the project. I came back later and tried to open it, through File<Open but it says there was an error importing the data and I should try using Import Raw, so I tried this also and it comes up with a blank file and everything that I worked on it just gone. If anyone could help that would be much appreciated because as of right now im completely lost. Thanks!

Please answer the questions in the pink panel at the top of the page.

Did you shut down the computer at the same time as closing the project?

Please attach the AUP file so we can see what is in that. Please see here for how to attach files:
