Here is the way to solve the "version does not match" error.
Step 1: If you were using the "hosts" fix solution, undo or just replace with the original file
Step 2: Download PATCH & install into "C:\Program Files\Subagames\Pristontale_I"
(OR MAKE SURE IT'S THE SAME FOLDER WHERE YOUR PT IS INSTALLED)
Step 3: Run psupdate.exe and PT should update to Ver: 3.12.6
Step 4: Run PsTale.exe
