GPU debugging issue with SDK 3.0

Hello everyone, I have a problem that I realized only yesterday. I have a solution built with Developer Studio 2008 with Nvidia CUDA Sdk 3.0 and emulation mode is not working any more. Moreover, I cannot use the Parallel Nsight since it does not support my Quadro graphics card. So what am I supposed to do then in order to carry out the debugging? Should I install SDK 2.3 once more and use an older version???Please any idea is greatly appreciated!
