Hello and thank you for watching and comments watchers! and sorry I cannot reply to all comments.
My tablet is old(still using Intuos2) so it has fatal problem. Same thing as this( http://www.conceptart.org/forums/sh.....78#post3721878 ) happen often recently, I did any way problem solving but I was not able to fix it.
I can do some drawing process by "Eraser" side but I need to get new one. I hope to get new one asap.

And I made ko-fi page some weeks ago, Please check if you willing to do support me. I'm very glad if you to do it.
