Task Scheduler insufficient permissions(?)

Windows Server 2012 in a domain environment.

I cant seem to be able to do anything in Task Scheduler anymore. I might as well mention that my user is a domain admin.

When attempting to disable a present task I get:

"The user account you are operating under does not have permission to disable this task".

When attempting to create a new task with just about any user including the SYSTEM account which I had used numerous times before I get:

"The user account you are operating under does not have permission to disable this task"

The funny part is that deleting a task does work. What could have possible went wrong here?

Update:

I discovered I'm having issues accessing c:\windows\system32\tasks\Microsoft\Windows. It always gives me "Access Denied" even though I've taken ownership over the folder for some reason.
