That is where I found the information, but it didn´t help me. That´s why I posted this question...
When those solutions didn´t work, what do I do?
I know Windows Vista may not be the best enviroment. Maybe if I Install FileMaker on a computor whith maybe Windows 7, or even Windows XP?
I just wanted to see if anybody knew why it didn´t work when I did what it says in the forum.... (on Windows Vista)
