Element 3D – missing all media elements Error

Hello experts,
Just I have installed E3D on my PC with AE6. Then I installed the Pro Shaders with Motion Design pack.
After that, the effect looks to run very well and also the license key worked in the first time but the media is missing.
All of the browser windows are missing Materials, Models, Environments or Bevels. Then I have attempted re-installing the fixed but no change. Now what should I do?
Do I require registering the position of the media files? Where am I able to get them on the hard disc?
Maybe it is not connected but I saw that the installer (zipped) is below 80Meg.

Unexpected Error
Thanks in advance.
