Hi everyone again! Well, I kinda of find solution, at least for myself, and you can watch it here [link] (screen shoot) Hope I would be able now to draw more or less normal way.
For now I installed wacom tablet driver for win7 ver.6.1.7 (extremely old one), but suppose it have no big different for me in this case. Maybe I just one from dummy population))
But well. all in all, Wacom Tablets have some bug in drivers, and if after installing the newest one you suddenly lost pen pressure, just go back to the wacom.com and download the driver below. After restarting PP have to work properly. Also don't forget to check your preferences in editing program.
If you will have another solutions, please, comment this post! XOXO
