Basecamp no longer working with latest update

I was prompted to install an update to Basecamp on Sunday. Now it won't work, with an error Entry Point Not Found, then loads of gobbledegook about:

The procedure entry point ?erase@ExifData@Exiv2@@QAE?AV?$.......... etc could not be located in the dynamic link library exiv2.dll

I've emailed Garmin and tried re-installing from the Website. No joy. Has anyone got any ideas?
