Cannot Parse File - .RAF

Hey, 

I often use Photoshop to edit photos quickly... I'll take 30 - 40 photos of a product and it's quicker to pick out and edit the 4 or 5 I want individually in photoshop than it is to create lightroom catalogues etc. 

Anyway, after years of doing this - suddenly, about 90% of RAF files (Raw files from Fuji cameras) won't open. It just says "Could not open “filename.RAF” because the file-format module cannot parse the file." 

This is happening from two different cameras /cards - so it's not just one card. I can't seem to find an answer or solution for this happening anywhere. Photoshop and Camera Raw are all up to date. 

Please help - driving me insane. 

Thank you!
