Subtool master not loading

I get this message when i try to open the subtool master script( the rest scripts work fine) and it doesnt load .
I tried reinstalling ,restarting, deleting the script and also replacing it with the subtool master script from the download center.
I use zbrush 3.5rc3 in vista 64 .

Thanks in advance.
