FrameMaker 10 crashes when opening files with Internal Error 10024, 9323487, 9022944, 9008636 (leaves files unrecoverable)

We're running unstructured FM 10 on a VM, Windows 2008. This morning, while creating a PDF of a 700+ page book, we got an out-of-memory error and after that, we are unable to open any file in the book without crashing FM. Since we can't open the files, a MIF wash isn't possible. Our VM had 4096 MB of memory (most of which was consumed) when this happened. We increased it to 7168 MB, but it seems like some serious damage was done to the files. Of course, we have an upcoming product release (FrameMaker seems to be keenly aware of deadlines). Any ideas on how to recover these files? We can resort to a backup if all else fails.
