Prepaid phone question: Samsung Smooth on verizon network HURRY!?

OK, i activated my phone, then after a month, i put more money on it, then it ran out. For about 3 months. Now, i want to reactivate it and when i go to My Verizon by pressing the up key, it says: "invalid host specified" and it won't let me on. What do i do? can i go somewhere else (verizonwireless.com/myverizon is being a terd. I tried to make an account, but it has to text me for that, and my phone is unactivated, so i can't recieve it!) grrrr! please help! :(|||how about dialing *611? I think that will work. Otherwise, take it into the Verizon store and they will help you get set back up.
