If you're on a different server and want to use this one say, how do you get it to run? X.x I know that probably doesn't make sense but the heRO.exe won't let the game run, if I delete the 0=heRO.grf from the Data file and leave the adata.grf it runs just fine..but on the other server ;.; how can I get them to both coincide?
I wouldn't mess with the data file. And if you have a data folder, then delete it cause that will mess with the game. A lot of the time if you have more than one server in the same folder it wont work. And last but not least, make sure you have kRO and kRO Sakray updated.

As other mentionned, it's best not to have multiple servers in the same folder.
But if you insist on it, when you remove the "0=heRO.grf" basically you are removing the line that says to connect to our server, so the other server in the folder takes precedence probably. Make sure you don't have a folder called "data", if you do, rename it to something else (anything).
If that still doesnt work, post a screenshot of your RO folder and we'll assist you as best as we can ^_^
