编程失败

我有一个CY8CKIT-050，它通常在我的Windows Vista机器上运行。
突然，当我想编程一个已经完成的项目后，所有的程序块，我收到一个“编程失败”的错误，暗示通信丢失。
在另一台PC机上使用Windows 7的测试表明，该板是正常的，可以被编程。
有人能告诉我在我的Vista创建者2.1安装中要改变什么以使它再次工作吗？

  I've got a CY8CKit-050 which usually worked as expected on my windows vista machine.
    Out of the blue when I wanted to program an already working project after programming all the blocks I received a "programming failed" error with the hint that the communication was lost.
    A test on another PC with windows 7 showed that the board was alright and could be programmed.
    Can anybody direct me what to change in my win vista Creator 2.1 installation to get that working again?
