Well it did make a difference, your host’s server is now allowing wordpress to execute the CSS file. THe only reason you blog isn’t looking right now is that there is a problem with the ofrmatting of your CSS file.
Did you change anything in the file? How are you uploading your wordpress files? I perosnally use an FTP client like SmartFTP (https://www.smartftp.com) to do all my uploading, and I have never had a problem.
My suggestion is to completly reupload a fresh, unedited version of the deafult theme and activate it. If that doesn’t work then perhaps you should completly reinstall wordpress via an FTP client, rather than fooling around with Binary and ASCII modes.
