Cannot Open WD SmartWare on MacBook Air

I partitioned my drive using Disk Utility (OS 10.5.8), after installing WD ‘Smartware.’ The icon shows up top, but Smartware freezes when I try to load it. 

Please do clarify re “make sure to download the disk image back to the drive.” What you do mean, where is the image, what does downloading it back entail, etc. 

Thanks in advance!
