Where can I find the Smartware version1.4.5.2

It seems that Smartware version work for me. Since I erase the drive on ‘My Book Essential’, I do not have that program came with the drive anymore. The updater does not work well for me. Can anyone send me that program.

Is not possible to update to prior versions of smartware

I have the latest version and works well… 

What problems do you have with the new one?
