Have you updated the driver for the 1010? I think there were some issues with the early XP drivers for this card. I still use ME myself, and I use Cakewalk.
If you do update the drivers- delete the 1010 from the computer before you install the new ones. If there is a README for the driver, follow the instructions exactly. There used to be some uncommon instructions with the Delta cards (stuff like installing the driver, THEN installing the card when prompted by Windows). I don't know if this is the case with the XP drivers, though, so check the instructions carefully.
Also- a lot of PCs use an IRQ sharing scheme because there are more devices than there are IRQ's. These schemes are usually driven by the PCI slot you have the card in. Look at your BIOS and see if the Delta is sharing an IRQ (don't look in Windows- look in the BIOS). Sometimes all you have to do is change slots with the card. It also helps to make sure that any unused devices in your PC are disabled (stuff like extra com ports or USB ports, RAID controllers, etc.) This is where having a dedicated PC for recording comes in handy!!
WARNING: If your not sure what you're doing in your BIOS, ask before you do anything!!! You can really screw your computer up if youdon't know what you're doing in here!!!! :shock:
Your Delta should work. There is a great troubleshooting on the Midiman website here:

Look at all the posts marked "Delta Series" not just the ones labeled for the 1010.
Let me know if you need any further help, and I'll be glad to try!! :D
