It seems that you're using an outdated browser. Some things may not work as they should (or don't work at all).
We suggest you upgrade newer and better browser like: Chrome, Firefox, Internet Explorer or Opera

Create the directory 'Saves' in c:\program files\\Broken Sword - The Sleeping Dragon\
Thanks man, it works perfectly, I can finally move forward.
If you have installed the game in a different folder, this path might be different.
The Folder Saves must be at the same location, where the "BSTSD.exe" is. Maybe it's possible to modify the install script so that this folder is created during the installation!!
Thanks for the Tip. I try since 1 hour with many manipulations before find this solution.
