zip file isn't working???

I recently joined the VUSCG and downloaded a zip file containing files that needed to be added into the scenery for FS9. First I made a folder as it told me to do. Next I put two folders into the MAIN folder that where SCENERY and TEXTURE. I put the appropriate files in the appropriate folders and put the folder in the FS9 MAIN SCENERY like it said to do. I then added it to my scenery and I do not see the scenery. I have tried many things, but maybe one of you that knows more about computers can help? ThanksBrooks
