Strange error: failed to load unit 'pgm'

I'm trying to wake up a VM from a snapshot (state: turned-on) and all of a sudden I get this error:
- VBox_error.gif (17.45 KiB) Viewed 2972 times
Anyone has any idea what does it mean?
Thanks in advance.

There is a difference in the saved state and the now state. You can post the complete log file ( as an attachment ) but in the end you will need to discard the saved state.
Things to check:
Host drive ( is it full )
Host drive for corruption.

Thanks for taking the time to look Perry.
Absolutely no chance of "disk full" (either VDI or host's) so looks more to the corruption side.
The referred "shot" is shot #7 in a cascade of progressive shots. Previous shot (#6) is the same but before turning on the VM, so it's an "OFF" state shot, when restored, it BSOD's. I've gone as far as restoring shot #1 (OFF state) and BSODs too, so the corruption should be in the first {xxxxxxxxxx}.vdi of the chain.
When I boot from an external disk and "view" the supposedly corrupted disk, the files are there. I can copy/move them, etc.
So any chance of doing something about it? It's an important image and I have no backup. It's not about data, it's the "system" which is important, which contains many programs configured in specific ways.
