If you receive this message, your server administrator has not established your permissions correctly. You will need to call the server administrator to reset the permissions. Every time an FTP account (for uploading your Web pages) is opened, your server determines all the things that you are allowed to do, like upload, download, write to a file, delete a file, make new directories, etc. If permissions have not been set up correctly, it will cause these types of problems.
If any transaction you try with CuteFTP doesn't seem to be accomplished, refer to the log (the lower part of the remote pane in the CuteFTP Professional window, and the top window in CuteFTP Home) for any entries that are colored red or any message boxes that appear indicating a potential problem on your server's end.
