Camera Raw no longer launches Photoshop when I click the Open button.

I found the problem. After playing around for a while, I discovered this only happened to the RAW images in one folder. (FYI, I only had RAW files in that folder.) The problem was that folder’s name had an apostrophe in the name. Example: UncleJoe’sFarm. When I remove the apostrophe, launching and transferring the image to Photoshop worked as usual.
