Found a post that said you had to push the .exe's into Windows 7 compatibility mode and add run as administrator rights.
So for me, from here:
C:\MyGames\Revelation Online\game
5 Files changed:
cport.exe
tianyu.exe
tianyu_p.exe
tinayu_rs.exe
typrotect.exe
left click to select the file, then right click -> properties. Compatibility tab; run this program in Windows 7 and check box at the bottom, run the program as an admin.
After that I could login and play just fine.
If you're having problems...
