youtube-dl 2015.12.31 does update over and over again

[Klaus1189]

2015.12.31 does update again and again if youtube-dl -U is used. Never had this behavior before.
It doesn't seem to recognize that it is up to date.

Works fine for me:

C:\>youtube-dl.exe -U
youtube-dl is up-to-date (2015.12.31)

Post the output of youtube-dl -v then youtube-dl -U.

I have to use youtube-dl.exe -U instead of youtube-dl -U, but in the past the second worked for me. Strange.

I tested 2016.01.01 -> same behavior. I need .exe now. But why?

[Klaus1189]

I know what was wrong. I got another copy of youtube-dl.exe in the same directory but without extension. I don't know how it came there but I deleted it and it was good.
