Office Store not working in Office 2013 ProPlus

Question

I have few policies set up for managing our network deployment of Office 2013 ProPlus. Pretty standard things like disabling the first time run movie, disabling the office start screen, and disabling OneDrive. I actually made most of these changes through
the registry as well.
Now, it seems as though the Office Store is disabled but I have no recollection of specifically disabling such a feature nor could I find a registry or GPO which does disable it. I even undid many of the registries I use on a test bench but still could not
get the Office Store functionality back. We've had Office 2013 rolled out on our network for almost a year, and it's taken this long for 1 person of 150 members of staff to notice that the Dictionaries feature is not working due to Office Store not working.
I feel a bit daft posting something seemingly so trivial on TechNet, but half an hour on Google didn't turn up anything relevant that I wasn't already aware of.
Many thanks in advance.

Hi,
Please check if you have disabled the option of "Don't allow any apps to start" and "Don't allow apps from the Office Store to start" in Office Trust Center.
Location: FILE->Options->Trust Center->Trusted App Catalogs
GPO settings for these options:
Block Apps for Office
Block the Office Store
Location: User Configuration->Administrative Templates->Microsoft Office 2013->Security Settings->Trust Center->Trusted Catalogs
Hope this helps.
Thanks,
