Youtube not working anymore ?

I dont why but I cant download some videos which I download earlier. need help

非常不错的插件，可以下载很多视频和音乐，非常感谢

buon plugin comodo

I like Video DownloadHelper. It helps me to save video I need and suggests two ways of saving: by browser or companion application. Without quality loss (or I don't see it))). But not always I can guess what video I should download, if there are several videos per page. And it stopped asking me what method of download to use, though I use the setting "Ask".

非常好用的軟體

how the fok i can see where file is saved and if it was? the worst UI winner goes to this app.. total mess please redesign it and make it user friendly like it was in past, you did total mess... im very disappointed son..

Brutal!!!
La he utilizado en muchos sitios a parte de YouTube y nunca me ha fallado; sin duda alguna la mejor herramienta para descargar videos.

The most flexible and useful download manager I have.

it's good !

Works as expected. 5 stars from me!

Bom, porém o download deveriam ser mais rápido.

This was fantastic fror years now they're wanting you to pay for it and are putting a watermark on videos you download. Ive deleted it
2 years later - Now they're wanting you to download another program or it doesn't work - stuff it. I tried it again. Still as bad as it became. Theres better that don't do this

GOOD
