I found that this helped me, but let me clarify, you need to move or remove the file from the folder.
For me, it was in the Ragnarok Online folder where the client is installed to. For example, find "Raganrok.exe" and the .dll will be in the same folder. Once you find it, you could either delete it, or move it to a different folder, just in case something breaks without it. Thanks to kayderim for discovering this.
