I think I found the problem. Inside the zip file the folder is labeled 1.0.8, but the sub-folder inside that, the one that has the guts of the mod is labeled 1.0.5. I renamed that folder to 1.0.8, and all seems to be working fine. Perhaps, I am not installing my mods the proper way, but that is how I fixed it. Thanks for your help. It pointed me in the right direction.
