We are currently re-writing the client with a newer release of the Refactored RS client, I got it from one of the MoparScape Moderators, and it was refactored by MoparIsTheBest himself. (The guy who made MoparScape and MoparScape.org)
I am hoping that this will not occur after the re-write, and I am avoiding all cache downloading problems by writing an Update Server and Client to embed into the RS client that will download all cache and music files properly, so we don't have to worry about problems with websites, only the game Worlds.

But for now you can use whatever client you like, I'll post something in the News when the new client is done.
