Hi ne0t , I faced that problem , what must have happened that your internet connection must have been disrupted and then you reconnected and tried to download the same file again, and got that messege again and again, what you can do
1. please clear your cache of temporary internet files.
2.please clear all the traces from your system , for above two task you can use a wonderful free software Glary Utilities , google for it.
3.and if you are using any download software like free download manager please clear the traces and
history of downloads from there.
after that restart your system , it should work,
This technique can be also used with rapidshare who will always say to wait for 15 minutes
for the next download , hope that works
