Hi Boris,  
the youtube downloader gives an error. After the download is complete, it is not possible to download the output. An error 404 is given. I sent you the logs.  
Thx

SB

Did you send logs right after seeing this error on UI, can you click download and send logs right after that?  
Also is it any file or just specific one?

logs were sent after the error. I have sent them again.  
Here follows the sequence of events:

1. you add a new video for downloading
2. you select a template (f.i. default or audio only). In my case I have selected default
3. the video is queued successfully
4. the download takes place in the machine. After few seconds it is complete.
5. when you press the download button to get the output in your web browser, you get an error 401.

All these steps should present in the logs I have just sent. Thanks. In the picture you can see: the “complete” tag, the download button.

Ok I was able to reproduce the error, updated to the latest version and it should work now, redownload after the upgrade.  
It is is the usual catch-up game with YouTube changing constantly.
