That was nice of you, but we're actually not idiots. We know *how* to download. What we can't do is either get past the endless captchas, the "session expired" messages no matter how fast we do the captchas, the 403 Forbidden errors, the blank page with "IP" in the corner, and so on and so on.
I also see you have no apparent web protection. That is unacceptable for some of us. Also, I use BitDefender, which cannot be turned off and whitelisting douploads and solvemedia made no difference except to show a bucket of ads. I've tried turning off ad-blockers and Ghostery - no significant change.
I strongly suggest JDownloader plus their web interface for upload4earn. The process takes longer, but it does work. However, even JD can't handle douploads.com so that site is dead to me. If I really want the book, I may contact someone who's already got it (their names are right by the Thanks button) and offer a WRZ or more for a usable link. I'm willing to help too within reason.
I do not dispute the poster's right to use whatever file service they want. They just lose Thanks/WRZ if it's not accessible to everyone.
BTW, one of the mods sent 3 emails to douploads trying to get help from them for us. They never bothered to answer.
