I was finally able to get the program to recognize the files on the USB drive.  I ended up resetting the paths and then restarting the machine.  I guess the zipped files I have I'll just have to hand install, just like before, but that's ok.  Each time I do it I refresh my memory as to where everything is. 

Thanks for the help, everyone.  As always, the communities here are the best source and resource on the planet!  Give yourselves a hand!!
