I did a restart since I haven't shut my computer down in a few days. After opening Xampp, and running Apache, I then closed out the two tasks running. I opened my client and I got the same error. I also tried not running Apache, and restarting Apache. I continue to get the same error.
I also tried a fresh unedited client. It gives the same thing, so the client.swf is not the problem.
Edit: I also changed the server to be public, by giving it my hamachi IP. That did not work either, and port 2050 is not being used.
