Well, in this case I may have a solution for you:
First: open the posting on sanet and scroll down to the download links. On the right there are buttons to copy all links with one click:
Than open IDM and click on the menu Tasks and there on "Add batch download from clipboard"
A new window will appear:
Click on each entry or click on the button "Check All" to select the needed download links. Than press the OK-button.
A small window may apper like this.
Press the OK button to go on.
Finally you will see those previous selected links in your download queue.
That's all. Easy. Right?
