illegal characters refers to dashes in your name, just change your name doing /nick kas
it should let you change it if the name isn't taken at the moment, ignore what it says, you can register your name but that's not necessary.
after doing so you can join any channel by /join #roomname if it didn't connect you already.
give screens if you still get some errors
