I've just opened up my very first wallet on Blockchain and deposited 50 bucks no problem a few days ago, but now when I tried to do it again it says Invalid exchange. What does that even mean?

Anyone else having a problem with this site?
Blockchain.info/wallet uses external partners for making it possible to buy bitcoins.
Was this the BitInstant/moneygram (U.S.) form, or UK form, or what currency?
