Wrong file formats

I used the sparkfun scripts and was really happy that you guys posted it so I wouldn’t have to worry about the file types that I upload. Unfortunately, when I tried to upload a design to test out that BatchPCB would work well, it yelled at me something like “we’re cracking down on floating files. Only such and such file extensions are allowed”. The only difference in the extensions is that the ones listed were lowercase the sparkfun’s script gave uppercase. just changing file names didn’t help.Anyone know how to fix it? It appears no one else is having this problem which probably means I’m messing up on something simple.
