When I download the most recent Trainer for BL2 (188.8.131.521067 (10.22.2013)), there seems to be an issue. The trainer contained within the .zip file is version 184.108.40.206171, not the most current release.
I have tried downloading the file multiple times, even using different browsers, but still cannot obtain the most recent version. Is the download link just pointing to the wrong trailer? Link
