Style.css Not Found

Hi!

I created my own theme over the summer, and used Filezilla to connect my files. I just recently bought a Mac, and am now using Cyberduck. Once I transferred my files to Cyberduck, I received a 404 error for my style.css file. I have no idea why this is happening, and have tried to link my css in numerous variations to no avail. My file tree is correct according to the WordPress Codex.

Any ideas/suggestions as to why my stylesheet is no longer linking?
Thanks so much!
