Could you update to the new version, and retry?, we now support correct decryption in more videos.

Worked great, I put 2013.06.32 2629e14eaf961051c62c4760917c3bb2 in the CWD so I could run 2013.06.29 as well. I ran 2013.06.32 with v=bWXEufdBp30 and v=M82OAUouEUQ and they now both worked. There was some new diagnostic message about encrypted signature. Immediately after I ran 2013.06.29 again twice each on the same videos from the same computer and all four times it failed in the way it had five hours ago. I believe it is now fixed for these two videos. Thank you.

Example of success with the new version:

Thanks for reporting, if you find a video that continuously fails, post it, but first make sure you have the last version.

Very sorry, I thought it was the latest version on the download page cause I had downloaded just the day before. I should have double checked. Very much appreciate your help, thanks again.

Don't worry, it's better to report a fixed error than not reporting an unknow bug, specially with this specific issues we'd really appreciate videos that fail.
And I undestand you thought you had the last version, there have been a lot of releases (currently it is at 2013.06.33 ;))
