uploading issues

I cannot upload any files - I keep getting this message:

sfFTPShellExtension
failed to create Prepare File Operation Dialog

This happens with all methods of uploading

This also happens when I try to delete any files already on the website.

thanks - I have done that ( a few times) but I am having the same issues
