USBDM Target Connection Failure in Windows XP

My Operating System is Windows XP with Code Warrior 5.0 and USBDM version 4A to my interface. Now I am getting an error when I am working with the Code warrior in which I already have some codes downloaded in.
The error says that the target Vdd supply interrupted, please restore power to target. And it is asking me whether I will retry connecting or not. Should I retry then? I want to know whether someone else is having the same problem with me and how it was resolved. Thanks.
Here is a screenshot of the error:
