All of my VMs are unusable -same error!

[cherry]

Hello!

I have a lot of VMs (with Virtualbox latest under Win8 x64)-
Linux Win DOS etc.

All of them are unusable currently.
The error is the same:

How can I avoid these errors?

Thanks

I tried this trick no result.
I can't run any VMs.

Any other trick?

The error message suggests providing us with the VBoxStartup.log file. I don't see it here.

Zip it and attach it.

here are the logs (one of my VMs-Xubuntu)

Um. If you "tried this trick no result", then how come VBox.log says you are still using 4.3.20, and the VBoxStartup.log file says 4.3.26?

Download and try the 4.3.27 test build from here.

p.s. Please, in future we only need one log, otherwise we start billing you for the extra time spent on the question!
