InDesign file icons are generic white box
Yesterday I had a new profile added to my desktop (Win7) at work so that it wasn't under the old designers name but this morning I noticed that all InDesign files had been disassociated with InDesign. So, I did the whole "open with x program always" by browsing for InDesign but instead of the regular file icon, it now shows the generic white thumbnail with a tiny InDesign logo:

I've tried deleting/reinstalling InDesign and refreshing the icon cache, and checking out the other discussions on the topic. No success.
The files still work fine but it's mostly just an aesthetic issue. I need it to be fixed or it will drive me crazy.
Any help would be greatly appreciated.
