Software Update - WD SmartWare Version 1.5.4.5 for Windows (3/20/12)

I installed wersion 1.5.4.5 on a Windwows 7 64bit PC  4GB of ram.  
Restarted my PC and let SmartWare catch up overnight (Categorizing and Backups).

At first it looked like it is all beter (for a day).

Woke my PC up today (Same problem as before - Categorizing forevever - even though NO files have changed).

Same ram hog - peg cpu at 100% making the PC unusable.

New version of the software - same problems - what if anyting was fixed???
