While in the MATRoom, Poser 7 crashed upon selecting "Revert" to saved version of file...
then file became corrupted.

File contained only V4 with Hair (Amarseda)

If I try to open the file back with P7 it crashes, while with P6 it shows "no figures" in file.

P7 has the "use external binary..." option enabled

For your comments and sympathy...
;-)
