LDR-Importer addon error

Hi,
I have an issue with the LDR-Importer add-on for importing the lrd file, these are LEGO files used by the LDraw software.

1.I installed LDraw All-In-One-Installer from here:
http://www.ldraw.org/downloads-2/downloads.html

2.I Installed the LDR-Importer-v1.2.0 add-on from here:

3.Tried to open differents .ldr files but I got this error message in Blender:

So I tried to copy everything from this page into a Text Document, changed the extention to .ldr, and copy it in C:/LDraw:
http://www.ldraw.org/library/official/ldconfig.ldr

Now I just get this error message:

Same in Blender 2.70, Plugin can’t be enabled in 2.60.

Could somepony help me please?
