Ok, I have been trying to get mods to go into my SimCity Data folder, but they will not work. I have the SimCity Cities Of Tomorrow Expansion Pack. I have tried the Mods from Simtropolis. What am I doing wrong or isn't this program compatible with Mods? Please Help! I am a long time player of SimCity and would like to update the game with newer building, railroads, roads and much more. thanks Jim

I just recently received my Disc 3,4 and 5. I put the disk 3 in the D drive and installed it on my hd. From here I am totally lost. Can someone point me in the right direction to get these items installed so I can use them In my SimCity 4. There is an Thank you included with my purchase and it says to go to http://goo.gl/QWUL5C but nothing comes up. Is there a youtube video to help a person install these building, maps and other items included with the disk. Thanks for now Jim
