Crystal Oscillator on AD9852 eval board

Hello,

Is it necessary to solder the crystal oscillator to the Evaluation board for it to work properly?  My AD9852 Eval board was working fine with an external signal generator applied to J25, but I needed to switch to a crystal oscillator.  I inserted the crystal, removed the jumper off W3, but was not getting any signal from the board, so I decided to go ahead and solder it on.  Now the DDS does not respond to any command, even a master reset.  I checked that the crystal is on in the right configuration and that there is power applied to the board. Any ideas?  Thanks so much!
