After dMc on my new PC (Win 7 64-bit), the audioinformation displays wrongly.

The shell integration popup work fine if a file has a tag. (mp3)
If I remove the tag (using dMc), dMC show one tag (Track Gain).
This tag cannot be found in the file.

If I click properties/AudioProperties, only filename and filetype is shown.
Everything else is blank.
This applies to files with and without tags.

Apparently I'm running a 32-bit version of dMc (no choise when installing).
Shouldn't there be a 64-bit version?
