Can't seem to install it.

I don't know why but I can't seem to get the script to even install on x10host. I keep getting a 404 error.

Well sometimes x10hosting will not work without a little bit of modification of a simple script, read this thread for help. Note this is the case for some of x10hosting's servers, but not all of them.

If you still experience problems, lemme know and you can try MysidiaHost which is also free and better-supported.
