Getting a message that Photoshop can't open a file because Camera Raw isn't supporting lens profile

Question

For months, I have been using Lightroom 4.4, Camera Raw 7.4 with Photoshop CS5 and my Nikon D600 and Nikon AF-S Nikkor 24-85    3.5-4.5 lens.  In my LR workflow, I enable Profile Corrections and there is a drop down for the lens model as well as a profile.  Today, I am getting this message when I go to edit in Photoshop  
Could not complete your request because the file appears to be from a camera model which is not supported by the installed version of Camera Raw.
Please visit the Camera Raw help documentation for additional information.
I don't know what has changed, or what to do.  Need some help

Answer 1

In Photoshop CS5 do Help / About Plug-ins… / Camera Raw and see what version it says and if there is more than one Camera Raw listed.
Unless CS5 was a typo, PS CS5 only supports up to ACR 6.7 which does not support the D600 so that is why you’re getting that message.
Why you weren’t getting the message, before, is the question.  In LR’s preferences find the button that says something like Reset Warning Dialogs and click that, then the next time you try to open one of your raw files in CS5 from LR 4.x click Render using LR Adjustments and put a checkmark in Don't show this again, and you should be ok, although in this mode, LR creates a TIF or PSD (how ever you have it set up in the External Editors preferences) and PS opens that intermediate file.
