HELP. My thumbnails are gone!

[Gare]

I have no clue as to why two days ago, all my Xara Designer thumbnails have turned to the generic purple "X", shown in my attachment.

One thing: I installed a small program to force Adobe products to show thumbnails. PDFs, AIs, and PSDs haven't shown in years.


Anyhow, any advice or similar things happening to anyone?

TIA,


Gary
