Wacom pen sensibility

I've installed the new driver expecting the next one will fix it. I don't think it will.

I work with photoshop and a intuous3... yeah cave woman... but that's what I've got. I have to unistall, restart, install the drivers everytime it stops working in the middle of work. It makes me so tired. Today it happened 7 times.

I rushed to the wacom official site to ask for help.

How can I restore my pen's sensibily without restarting 1000 times?

I couldn't ask them... I had to insert the serial number. I turned my wacom upside down and saw a light spot where once... 11 years ago, there was a sticker with the seriam number...

o_o this has to be a cartoon soon!
