Yes, I am currently in coding of a Runescape private server. I am very new and have obsulutely no idea what I am doing when it comes to errors such as these. When I attempt to run my client for the server, it comes up with a command prompt, No Class Def Found Error: Client. So, I go to a different server, and run the specified client for it, and the command prompt this time says, No Class Def Found Error: EGUI.
What do I do?
