Lost all sky presets after upgrade?

eponica

Hi, I had a Carrara 8.5 pro 64 bit upgrade lurking in the DIM for awhile so I finally broke down and installed it. Afterwards I found I had lost most of my object folders and all of my sky presets, realistic and otherwise. Carrara is calling for the install disc to fix the sky presets and wizards. I got my object folders working by simply adding them again, but I am at a loss as to what to do to get back the skies...?? o_O; Do I have to reinstall the whole thing?

EDIT: They are still there in the Presets folder, I just can't load them from the side bar.
