Downloaded ExifMeta today, installed it into Lightroom 4.1 (64bit).   The install worked fine.   I'm running Windows 7 (64bit) SP1

I select some meta data fields - when I click commit - I get the following:

RC ExifMeta has encountered a problem.

Error message: ...ightroom

Please report this problem - thank you in avance....
