Your first problem may be as follows:
It seems that there is some kind of interference with Visual Studio Service Pack 3 and Windows XP with Service Pack 1 using CW DAQ controls. To fix this problem, try to uninstall Visual Studio and then reinstall without the Visual Studio Service Pack. After this installation is complete, your DAQ board should show up in the CWAI device list.
