I just upgraded an old computer that had Gigastudio 160 2.5 on it. I upgraded from W2k to Wxp. I'd like to keep Gigastudio working on this computer. Gigastudio opens, but it keeps asking me to register and receive the unlock code. I have this code (since I bought this years ago) but I don't know where I am suppose to install it. Without getting past this I think I am also barred from using the NFX programs.
