I have the same issue, but it’s because I have two SSDs in my system. Version 1.4.4 says it won’t recognize them if I have two. How dumb is that, because the prior version did just fine.
Anyway, SanDisk support gave me this link to download a prior version:
http://downloads.sandisk.com/Dashboard/v1/v1_4_3/SanDiskSSDDashboardSetup.exe
Hope this helps.
