[Cant use paint brush tool againe.]

Hi, 

I used brushes. Now I want to use Pain Brush Tool, but instead of the circle, the brushesh comes back.
Could someone tell me how to turn off the icon of brusches to use paint brush tool ?

[Software problems,]

After uninstalling and reinstalling the software againe, some functions no longer function goed.
I have to uninstalling the software a few times and re-instate it again. But that was not to help.

My Develop mersona does not look as it should look like. Could anyone tell me how do I get the old Confidential Develop persona back?
