Error when starting VirtualBox (Unable to load R3 module)

1

I'm aware this question has already been asked, but the answer points to a website that is currently down and is relevant to a VirtualBox version that's old and irrelevant to my version/problem. I'm running VirtualBox 4.3.28 on Windows 8.1 (all sys spec requirements are met), and when I try to start a new virtual machine I get the error: Unable to load R3 module C:\Program Files\Oracle\VirtualBox/VBoxDD.DLL (VBoxDD): GetLastError=1790 (VERR_UNRESOLVED_ERROR) >Details show:

Result Code:     E_FAIL (0x80004005)
Component:       Console
Interface:       IConsole {8ab7c520-2442-4b66-8d74-4ff1e195d2b6

The error log shows:

I don't know how much of that is relevant as I'm a total VirtualBox noob. Like, a complete noob, but any help would be appreciated.

Also, I've done a ton of googling but everything I found either didn't work or the site was down (VirtualBox's site is currently "down for maintenace" and has been for the past 24 hours).

Okay, I found a solution to my problem but not an answer to my question. Throughout my research I picked up on vague references to version/patch bugs so I downgraded. Downgrading seems to work.
