Its a connection error. You can look it up and depending on what system you have itll give u a troubleshooting method. Ive had error 2002 for almost 3 weeks nd I haven't been able to play even when using the troubleshooting method provided to me by square enix. I can't promise itll work but I hope you don't have what I have nd that you'll be able to play without flaw unlike me...
