Ultimate shoulder rides

Nick,i have been trying to upload 3 new clips to the archives many days now and it doesn't let me,it says that i don't have the nessesary permissions.I try to drad the file to the upload section,it starts uploading and immediately it stops with this message that it cannot upload and to check whether i have the permissions.I am sure it isn't with my ftp client because i tried with both cuteftp 9 and filezilla and it doesn't allow me to upload.What is the problem? Maybe you have to set the permissions on the server or what else,when i drag the file it beging uploading for a few seconds and then it stops with an error.This happens with anything i tried to upload and also with both ftp clients,cuteftp and filezilla.Can you please check it out?
