Just bought Pro access, I'm trying to trade on bitstamp, after I ran backtests and decided which algorithm I want to use, I clicked "trade" and attempted to login with my bitstamp user/pass as well as the bitstamp API key/secret.  Neither of them work.  I have the API key created with all permissions except for withdraws enabled under Security--->API access.  I confirmed the email to activate the key I created.

Why can't I trade on bitstamp  I really hope this gets resolved quickly since I just purchased Pro access.
