When I download the most recent Trainer for BL2 (126.96.36.1991067 (10.22.2013)), there seems to be an issue. The trainer contained within the .zip file is version 188.8.131.52171, 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
