SS4 File Corrupt

I was recently modeling a project and had gotten a good way through the modeling effort.  I made a small corridor and didn't like the vertical alignment.  I then tried to adjust a point on the alignment upward.  The program didn't like that and tried to crash.  I believe during the crash it tried to save itself (before I could hit clearcrash).  Now any time I try to open the file, or a file that references my design file, microstation hangs up then crashes.  

Is there way to recover my old dsgn file of say an hour ago?  I'd like to not have to go back a full day or more with our IT team to get me a working file.
