Can't Create/Open new File - Photoshop CC

Question

Hi there,
I just purchased Creative Cloud recently, went to go open up Photoshop today and it won't allow me to create new files or open existing PSDs:
Example: https://www.youtube.com/watch?v=QoWKJbIf3BI
I can, however, operate in Acrobat and Illustrator just fine.
I'd first googled around a bit to see if anyone else had the problem, noticed there had been a few threads. My troubleshooting steps thusfar.
     1. secpol.msc > Security Settings > Local Policies > Security Options > User Account Control: Run all administrators in Admin Approval Mode (disabled)
     2. Took ownership of Adobe directories at C:\Program Files\Adobe, C:\Program Files\Common Files\Adobe, C:\Program Files (x86)\Adobe, C:\Program Files (x86)\Common Files\Adobe
     3. secpol.msc > Security Settings > Local Policies > Security Options > User Account Control: Run all administrators in Admin Approval Mode (enabled)
     4. Trashed Preferences on startup.
Pertinent bits of info:
OS: Windows 8.1 (64 bit)
GPU: EVGA GTX 560ti (latest drivers)
Photoshop CS6 via Creative Cloud.
Any help would be much appreciated! It's working fine on my laptop (Mac OS 10.8) but the desktop is a little sketchy with Photoshop.
