1.It is working perfectly here . Would you please give us temporary wp-admin access via a private reply so that we can check out what’s going on there.

2. [wpdm_tree] short-code is to generate tree view of all categories. By giving [wpdm-tree category=’category-slug’] you can show specific category tree view. You can check it here http://www.wpdownloadmanager.com/doc/short-codes/

Please show them this url http://www.idesco.fi/wp-content/mu-plugins/wpengine-common/css/wpe-common.css
Their support should understand how their things work, this is in “wp-content/mu-plugins” dir, plugin dir “wpengine-common”, as it is in “mu-plugins” dir , it can’t be disabled from admin panel, reference http://codex.wordpress.org/Must_Use_Plugins
There is nothing to do with wpdm pro.

It will require customization of code and it is not too easy to explain here.

For that you need attach each mp3 file with package, not as zip

Would you please give us temporary wp-admin access and the url of the download page? We have to check it.

We will upgrade default sorting in future release.

Yes it is possible

Problem fixed. Your server doesn’t support Resumable Downloads & Output Buffering. I just disabled them.

#1. for dropbox you simply need to file size manually, but that will not cause any issue with downloading file.
#2. Sorry, not clear, but you should see the api key in Download Manager Settings page like following image:

You simply need to click generate and Save Settings. Then use the key for your app.

For user specific access control you will need this add-on http://www.wpdownloadmanager.com/download/advanced-access-control/ . But no such option to check buddypress verification, But it is achievable through some customization or with a custom add-on.

There is a add-on http://www.wpdownloadmanager.com/download/wpdm-web-hooks/ to add internal php hook
