Thnx Katana but that really didnt help a file location would really help (i.e. C: Program filesbla bla bla) and that doesnt tell me how to open it either

Im just gettin into Machinima and tryin to get sum programs put togehter so i can do sumthin but i cant get Map/ModelViewer to work. When i find the file after just downloading it it tells me i need to export it but i dont know where to export it to. Any help? Also i tried downloading the win.mpq file Oxhorn mentions but i get the same basic problem.
