The problem you are having is due to the fact that the templates_c directory was created by the server and therefore you do not have permission to delete it, or any of its subfolders. You'll also have this problem when trying to manualy delete any folders inside the /files directory, created if you are using the ESD module.

As a quick work-around, the only option I've found is to rename the templates_c directory to something else, like templates_c_undeletable folder instead of deleting it. Then create a new, empty templates_c directory and chmod it to 777. Chmod is a UNIX/LINUX command that sets file and directory permissions. To CHMOD using the poupular windoze program caleld WSFTP, simply browse to the item you'd like to CHMOD, then right-click on it and select FTP commands > CHMOD(unix) from the bottom of the list. A pop-up window will appear where you can set permissions via checkboxes and it will show you the corresponding CHMOD commands before you apply them. Hope that helps you out.
