I am responding to my own post here as in the other locations I tried to find help.
I was having some other problems with my Land Desktop 2008 previously so I thought that re-installing my program might fix any and all problems I was havnig. I believe that after doing the AutoCAD re-install, a default "land projects 2008" folder was created in my drawing directory. I currently keep all of my drawings in a folder called just "land projects" instead of "land projects 2008" since it’s no longer 2008 (I know it’s the name of the program). Since then, when opening any AutoCAD drawing, now that the new folder land projects 2008 was created, AutoCAD may have been looking in it for something. I don't know what, because it's completely empty. To fix this problem, all I had to do was delete that "land projects 2008" folder and my drawings opened up fine. There's probably some other issues associated with deleting this folder, but I'll have to figure it out as it comes.
