Hello,
As I did not see my answer, I searched and have found the link.
The link in the mail is incorrect. I am sure it will be fixed. But, until it is, here how to download it:
The link points to the file: SkinStudio_11_setup_sd.exe
However, the correct spelling of the file is: SkinStudio_11-fs-setup_sd.exe
Replace, in the link given, the bad name by the right name and you will be able to download it.
