I want buy ADDS 10 to finish re-partition of my hard-disk, however, I found the software can only support SP2 (it's your webpage: http://www.acronis.com/homecomputing/products/diskdirector/requirements.html), as my OS is Windows XP SP3. I checked this with so many people, someone said yes, in the meantime, others say no (even by the engineer in ACRONIS Shanghai branch office). It's really confused me! I must got the official answer from you, before I place order of ADDS. Your official answer (from HQ) will be highly appreciated.
