User cannot log in after vault client 10.0.3 install

Hi

Having a really tough time with an issue. A user got a new Mac running OS X 10.8.4, she originally had the vault client 9.0.2 which would not let her log in, no matter what combination of credentials we entered it would not let her in. So we decided to put the 10.0.3 client on her system in hopes that it supports 10.8.4 OS X, but now the Login... button is completely grayed out, the only thing available is preferences and about.

Help! Is there something we're missing with this? Thanks in advance.
