Saw different threads regarding this problem but they too old and I guess there are some new reasons to start again.

Im using DT 4.30.1. Before I decide to change my SATA mode to AHCI everything works fine, now after I changer mode and was needed to reinstall my XP SP2 by chance to XP3 I`m start getting this error 39 so now I cant use DT.
Tryed different methods described here - removing and installing 3.x version, complete uninstalling DT with removing settings - nothing helps. Btw, on the same comp Im running Vista 64 SP1 as a second OS and DT works fine there!
So I wonder if there any chance to fix DT under WinXP SP3 ?
maybe some ideas ?
