Okay.. ._. Some odd error.

I've seen this error before.

Go into your RO folder (whereever your ro files installed, default path is c -> program files -> gravity -> RO), and run setup.exe

This will create the registries necessary to play, you can also set your graphic card and sound options.

I'm 99% sure that will fix your problem

If not, you could always download our full installer, it works pretty well, it's in the download section of this forum.
