"The command camera raw filter is currently not available"- Editing 32 bit photos

All,

I use Lightroom and Photoshop to create HDR images by "Merge to HDR Pro in Photoshop"

I then would set the mode to 32 bit and click "tone in ACR", which would bring up ACR for that 32 bit smart object.

After updating my Lightroom and Photoshop today, I run into a problem. Photoshop says "the command camera raw filter is currently not available" after I click tone in ACR. It seems as though ACR will no longer let me use it with 32 bit images....

PLEASE HELP, this is how I do all of my professional work and need to resolve this ASAP. I have already tried reinstalling both Lightroom and Photoshop, and manually installing ACR to no avail.

Thank you!
