RO Gravity Error

[Loki]

Are you getting this error from both the patcher and the client or just the patcher?

If it has the class: novice at the bottom I have yet to find the true cause of the issue.

Many people have suggested the following and sometimes it works sometimes it doesn't:

Stuff to do before install:

make sure directx is up to date
make sure all video/sound/etc... drivers are up to date

after that's done:

Remove RO via the add/remove programs or the uninstall program. Install a clean up to date version of kRO's sakray.
Get the require dll pack or install kRO's main data to get the required dll's needed.
Patch both kRO and sakray BEFORE installing any server.
Run Setup.exe and make sure all the settings are correct and that the right graphics stuff is chosen.
Then install a server.
Patch said server.
Try to play.

I had a friend who recently had this problem with another server and I walked him through every possible combination of fixes even gave him multiple clients each hexed differently in attempts for different results but they all gave him this error. I told him to keep trying to uninstall/reinstall. After two attempts of uninstalling/reinstalling the problem fixed itself o_o
