It remember me a project with a corrupted file in one of my bins. I had to open the media files folder and test each clip on it. Once that I found the corrupted clip (Qtm movie player said "this is not a movie file"), I turned off the disk, and opened the project to look for that clip on my bin, to erase it.
I hope this could work for you.
That sounds like a damaged Bin document. Seems like when reading the Bin file, the App reaches the end of the file while it still expects some more data. Do you have a backup copy of the bin? Depending on how it is set up, the Media 100 application does write Backups of Bins into the Users->Document folder.
