wow, that's the gravity tm error of death. you need to fully update your KRO before installing HeRO client. if it's still corrupt then you may need to redownload KRO and Sak. Lol, I think Panda already covered taht though ;^_^
You might have to. You should only have one client installed into the RO folder >.> reinstall KRO and Sak into a clean folder on the desktop or something, then update them. then install the HeRO client into that folder and then you should be able to play.
if you get that error again after this then it meens that your download of kro and sak was either corrupt, or wont update, and you'll have to redownload them.
He basically doesn't have RO at all in that folder. It's just our heRO files + another server's files, but not ro itself.
Have you ever played RO before? If so you should have the RO files somewhere. If you just downloaded 2 server's patch (30 MB each) you can be sure you don't have RO (it's over 1 GB of space). Basically if the download was fast, you don't have the Ragnarok files.
Ok... on the home page for the forums there is a download section. You have to download KRO and Sak. You can get them from a server, or via bit torrent. once you have them you need to install them, and then let them update. Then you can install HeRO client into that folder.
Private servers use eathena to emulate the game. So if you don't have the game itself, then the private server's not going to work.
Honestly with all these problems don't use kro and sakray, go with Pandora's Full Folder. It's one simple install, just one...xD And you won't be confused with the unfortunate lack of English when installing KRO/Sakray. I'm going to give direct links so you won't download the wrong thing.
there's only two parts, the 12/13 parter is actually for those with bad connections, that way they don't get to 99% and then it fails on them or if their net disconnects during download then they don't have to start the whole thing alllllllllllllllllllllllllllllll over again. Sadly, such is life when a file is over a gig
