Getting Critical Error upon Login

[Griffin Sloves]

I just updated to Windows 8.1 and I have Virtual Box version 4.3.4. I'm have an AMD processor x64 operating system.

Everytime I try to open up virtualbox I get a critical error. it doesn't give me an error code or anything; it just tells me to come here for support. I've never used these forums so I'm not sure I'm even in the right place.

Anyway I've attached the text and image logs.

Does anyone know why virtual box won't start? Let me know if you need a screenshot or more information.

From the log files:

00:00:05.492687 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
00:00:05.492689 !!
00:00:05.492690 !!                 Guru Meditation 1155 (VINF_EM_TRIPLE_FAULT)

There are several bug reports already on this. The developers are trying to solve it. Search Google for "VINF_EM_TRIPLE_FAULT" and pick the most appropriate bug report and add your logs there.

Thank you so much! So it sounds like there isn't a solution. For now would you just recommend downloading an older version of virtual box? Or how can i get a working version of virtual box, because I need it over the next few days.

I've heard several people that they had success with VBox 4.2.x. Why don't you give it a try and see?

Or you can try turning off nested paging.
