If it's permissions then you should try the Take Ownership script. That's helped me out on many occasions.
Unfortunately, this did not work
I just know I'll get someone reply here soon saying I've messed up permissions or the files are corrupt or something. It's daft.
I could do what I wanted with my own files in XP/Vista
Just seems with every new version of Windows, I'm getting more restricted with my own files. First it was UAC in Vista (which, after disabling, was actually fine, I had full control of my system) but since 8 and 8.1, even turning off UAC isn't helping.
