I'm getting the same problem as this gentleman. Although im running the server on a linux box and the client on my windows,the client just lingers in task manager with around 40mb loaded in ram. I'm using the latest kRo files (01/13/2016) with 'recommended setting' diff 2015-09-16aRagexe. The server seems to be up, but i have yet to connect to it successfully. I managed to get a Ragnarok server running when i was around 15.. and i cant do it now when im in my twenties. I will probably try an older client tomorrow after i get sleep. Meanwhile any help is appreciated.
Why cant they just release an offline version of Ragnarok? not everybody is a wizard.
Edit: I mean share, the tutorial is very difficult to follow not to mention if it's 100% working, judging from the comments.
