Someone is actually selling Camera Raw presets? Interesting.
Did they say that these presets are specifically compatible with the version of Photoshop you're running? Somehow I am imagining maybe they were developed with the latest version of Photoshop and yours is an earlier version (i.e., that the stored settings are for Process Version 2012 and your version doesn't understand them).
Is your Camera Raw fully up to date with the latest update released for your version of Photoshop?
I bought them from LilyBlue. I thought it would save a ton of time from having to open in Photoshop. I have CS5. Here's the specifications from the purchase.
WHAT VERSION OF PHOTOSHOP DO I NEED FOR LILYBLUE ACTIONS? FOR LILYBLUE RAW PRESETS?
most lilyblue actions have been developed for cs and above. lilyblue raw presets have been developed for acr (adobe camera raw) and adobe lightroom. both versions are included in your purchase. they work on both pc and mac.
OH. And I have Camera Raw 6.7... if that's helpful.
The only thing I can think of, beyond a basic version incompatibility, is that you may have unpacked the files improperly or that somehow they've become corrupted.
Seems to me you're going to need to take it up with the folks that sold you the software. Perhaps they have created an updated version that's compatible with Photoshop CS5 / Camera Raw 6.7.
