TI Calc Help

I just got a TI-84 silver edition calculator. Now I am trying to install a game on it. Whenever I find a game file, it is always under 83, which I am assuming is a compatable version. Now, I got the game from ticalc.org, its call reuben quest 2. I unzip the game, but when I try to send it to the calc like it says in the readme for the game, i keep getting a error message saying the connection failed, and it gives me the option to retry, skip, or quite. Everytime I retry, I get the same message. Am I doing something wrong? please help!
