Immediate error when trying to render in Sony Vegas 12 - An error occurred while creating the media

[Mooe94]

Today something weird started happening with Vegas 12. I was mucking about in my recent project and when I finished I pressed "Render As" and then this error came up:

[B]An error occurred while creating the media file . Exception thrown by method called[/B]

It's been around 2 months since I installed Windows 8. Vegas has been working flawlessly until now.
I tried rendering different projects (both empty and with media files), restarting and reinstalling Vegas but the error still came up. Then I tried Ctrl + M (which means Render To New Track) and then this error came up:

[B]An error occurred during the current operation. An exception was thrown by a type's initializer (.cctor). [/B]

I also Googled on the first error (the second one didn't give any good results) and came to the conclusion that it might be the K-Lite Codec pack I had installed MONTHS ago. I tried uninstalling the pack and removing it from the registry as well but no dice.
Some users had said that only reinstalling Windows helped. So I tried Windows 8's Refresh; and it worked!
I carefully selected programs I wanted to install using ninite.com - and I accidentally selected MPC with decoders (included were MPC). After installing everything Vegas no longer worked, same error.

So I did a second reformat, went to MPC's website and installed it without K-Lite (I presume the installer doesn't install codecs, since it didn't give any information on it or anything). Vegas 12 still worked. I preceded to install various Adobe software (Photoshop, Audition, Premiere, After Effects, Media Encoder, Illustrator, Lightroom), DayZ Commander, Mumble (1.2.4 beta), Fraps and other software I'm not completely sure of.

I rendered my project again. I opened the file and then I noticed there were some black frames in the clip. I re-rendered everything but it got worse. Blacks frames to and fro, glitching and other shit.
Then I tried a third time. The error came back.

Now, to recap, [B]I have not installed any codecs[/B]; only drivers and various software (there's a full list below). What the HELL is going on? I'm beginning to speculate it's Windows Update doing some hidden updates, but I doubt that's even possible.

(List is in no particular order I presume since Windows only dates programs by Year/Month/Day and not hours/minutes)

And inside HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32
I presume this is were codecs which are installed are located.

I found a temporary workaround for this issue. Options>Customize Keyboard >> Find the key which is called 'Batch Render', and bind it to a key. Use that key combo and you'll be able to render video, this worked for me.
