so i have been playing RO2 since last week. and from the very first time i ran RO2 client. it doesn't patch . so i've found out that you need to run HSUpdate application which is inside the ro2 folder.
Steps:
1. Run HSUpdate as admin
2. Run Ro2 Client as admin
kaboom.. then ro2 client will work.. but somehow , sometimes it might also fail . and i've also found out that u need to restart your pc
and try to do the steps again.
STILL>>>>>> this is very inconvenient , i hope this can be fix .. i feel annoyed every time i want to play ro2.
Cheers..
