First we'll work on some terminology - You mean you have the RBII Valueline CD?
Or you got it from SOLDOUT SOFTWARE?
Did it install, load and run OK as a STOCK install?
If you went ahead and loaded patches from your old machine there may be conflicts in the various SETTINGS with a new,different Graphics card, etc.
The main one being screen resolution (you're not using a new machine with an old monitor are you? An old monitor may not support the resolution that a new machine is capable of).
The only issue with XP is the lack of sound when using a USB joystick,so XP's not causing the DTD.
You'll probably want to be using more than one install of RB - maybe one for totally STOCK, one for FCJ, one for HASP, one for WFP, one for MMP......etc. So check out the Multiple install guide linked in my sig and refresh up on the newbie pages too since they've been improved.
You can check out numerous sites for info specific to RB and XP, the Hell's Angela site has a good source. The 'Wings of Valor.net' site has lots of good info.
