Virtual box has stopped working

[Aaeroln]

I installed virtual box and had XP running on it. I hadn't used it in a while so I'm not sure when it stopped working, but I installed Andyroid and it wouldn't work. I thought it was just Andyroid, but I noticed virtualbox wouldn't open XP either. Since then I have uninstalled and reinstalled every way I can think of both with the latest virtualbox and older versions. I can't figure out what's wrong or what changed. It used to work flawlessly and now even with a clean install I cant get it to work. Any help at all will be nice. When I set up a virtual machine and then try to open it for the first time to install the operating system I get the message in the picture I attached. I'm very frustrated thanks in advance to anyone with some help.

Also, take a look at the discussion: Windows 4.3.20 specifically for errors due to security. You might find some newer test builds and/or other helpful hints.
