I'm fairly new to this so I'll just get that out of the way. I downloaded the wallet and now it is saying "out of sync, syncing with network, 42 hours behind." Just want to know how to resolve this issue so I can deposit my coins from the exchange. When I try to send currently I get "This is an invalid address.  

Edit: Nevermind I fixed it. Read the steps and figured out how to do the addnode thing.
