@Senzury hi im portuguese i finally couls enter but i had to do a could a couple of stuff to enter
1 - after download i changed the owner of the files to my user ( the otp_notice_na_rtf.rtf, on both and problably on pso2.exe u habe both too), theres guide to say how is done ( ah and also u problably u may need to change the on the windowsapp folder to acess it to)
2 - after that make sure your user has full control on it if dont add it, i also add it the admins user with full control just in case.
then launch the and for it checked the files so might take a while
after it made an error about direct x i just downloaded the direct june 2010 and worked just fine
but after that appeared another error:
"Vivoxsdk.dll is missing"
and theres the steps for these
Open PowerShell in admin
Copy this and press enter: cd "C:\Program Files\ModifiableWindowsApps\pso2_bin"
note: change "C" for "D" or the disk where you installed the game
Copy this and press enter: Get-Acl pso2launcher.exe | Set-Acl pso2.exe
Copy this and press enter: Get-Acl edition.txt | Set-Acl otp_notice_na.rtf
i did all that and now i can play
Good luck for all
