1. Seeing this is a Question for Red this should have gone to him in a private message. But your new so mistakes can be made. You know for next time.
2. (first question about the mods) Did you unzip the files and read the readme? With the new planet mod some of the files will be need to be placed in the "modules" folder. Namely the ".mod" files.
3.Also if the files are .rar files did you unrar them? Rar files are like zip files but you need a different program to "unzip" them. Winrar www.rarlabs.com
is where you can get this program if you need it.
