Digital Painting Help Please..

Hi all, I have just sat down to do some digital painting and plugged the wacom in, its all setup correctly, but the brushes arent changing to 'pen pressure' on the tablet? Any help please? I set it up the same as I set it up before but I am just getting the one size instead of variance...

Heres the Settings..

*& ive turned on dual brush.. to give my brushes a different 'texture' to them..

Please help ASAP thanks.

just found out theres a strange '!' icon next to them. the tool-tip says I need a pressure sensitive tablet to use the features.. Now correct me if im wrong but intuos4.. is..

*ahh maybe drivers... will download and try again..*
