Hopefully i have posted this in the right forum

I bought the 30 day vip membership yesterday, but when i try to download a file i get an http 404 error

Can you download these links with your browser?

Did you enter your account in jD and Enable Premium globally?

What about some example links and a complete and detailed log?

Just tried in my browser and i get an http 404 error, in jdownloader nothing happens just sitst here saying 0kb/s

If a link is "Not Found", because this is the meaning of the http 404 error, then jD can't find it neither.

If you want jD to handle this type of error properly, please read the last sentence of post #2 again.
