AD9915 SPI Control through LabVIEW

I am trying to control the AD9915 Eval board using SPI from labview. I write all registers, toggle IOUPDATE, calibrate the PLL, toggle IOUPDATE, calibrate the DDS, toggle IOUPDATE and nothing. I've been trying to replicate the process I gathered by sniffing the SPI bus with the cypress controller active, but I'm not seeing success in replicating it. Am I missing a step or a process to getting output?
