Yiynova MSP19U+, Paint Sai v1.2.0, and Pen Settings Fix
Update 1/24/16: On Windows 10, I started having my Tablet driver crash, (under the program that comes with Windows)“Event Log” had it listed that WTClient.exe keeps crashing (one of the files that is necessary for any drawing tablet to run). I tried everything for months, and magically it worked today. The steps that were new was that I had to move my computer to install a new desk. Everything was unplugged and plugged back in as well as tightened (Yiynova Monitor), but I made sure to put the Yiynova USB cord to be in the 3.0 slot. It may be a USB port issue, this is untested. I know in the past I had faulty ports from age/overuse/watt compatibility issue, so try putting it in a 3.0 slot or a new USB port in general.
These are steps that worked for me personally to fix having little or no pen sensitivity on all programs and the offset cursor when using Paint Sai v1.2.0 with Yiynova MSP19U+ (a drawing monitor tablet).
Instructions For Windows 7
Install newest Paint Sai 1.2.0 on your primary driver.
Download the latest tablet driver directly from the 3rd party "UC Logic" with Penates. http://www.uc-logic.com/index.php?lang=en&action=support&cid=6
Extract .rar and install (if it errors that it can't find a file, put the main folder on the desktop to shorten the address).
Open UC Logic tablet settings, "C:\Program Files (x86)\TABLET\PLaunch.exe" and adjust to your choice of monitor, sensitivity, hotkeys, and calibration.
Hit okay and exit tablet settings when done.
Open "C:\PaintToolSAI\misc.ini" and change "TabletMouseSimulation" from 0 to 1. The rest is default.
Open Paint Sai, the offset is gone and the pen sensitivity should work as well.

If your PLaunch does not open, type in "Device Manager" in the search bar at the bottom left and open it. There should be a small icon that has a yellow triangle with a black "!", extend that system device and right click the "Unknown Device" that also has the yellow triangle and choose "Update Driver Software...", this is most likely the Yiynova Monitor. Choose "Search automatically for updated driver software" and it will update the driver automatically with success. Tablet Pointing Devices/Tablet Monitor will appear on the list and the unknown device will disappear. Try opening Plaunch.exe again.
Hit okay and exit tablet settings when done.
Open "C:\PaintToolSAI\misc.ini" and change "TabletMouseSimulation" from 0 to 1. The rest is default.
Open Paint Sai, the offset is gone and the pen sensitivity should work as well.
I have not and am not planning to make instructions on Windows 8 or other systems.
If all else fails, you can use this method. This was intended for a mouse to mimic the effects of pen sensitivity on Paint Sai:
