Outdated.

Sorry for confusing. Before creating ticket I've executed youtube-dl.exe -U. Application had printed something about "downloading 2017.05.01" and "waiting for closing handle" and had exited. That did not help.

Then after I've created a ticked I run it once again and noticed that version is wrong. How....?
Anyway, v2017.05.01 works good. Thank you very much.
