VBox gets an error opening ALL OSs?

[nirost]

Okay, so I'm having a small giant issue with VBox. I deleted the problomatic file (VBoxDD.DLL) then repaired, even reinstalled VirtualBox, but still no luck with the system. So here's the error

Failed to open a session for the virtual machine SteamOS 64.

Unable to load R3 module C:\Program Files\Oracle\VirtualBox/VBoxDD.DLL (VBoxDD): GetLastError=1790 (VERR_UNRESOLVED_ERROR).

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

In case you haven't noticed, I'm using a SteamOS beta. This was using the presets for Darwin 64 bit, but modified using a guide on Steam from the user "rebelholic" (No quotation marks) [No URLs until day 2 of my membership ]
I am just trying to figure out what went wrong and fix it. Any help would be appreciated, so thank you in advance
