Uploading

I get this message when trying to upload to cdrom with WS Ftp-

553 /.2/idgames/incoming/file.zip: Permission denied. (invalid filename)

I dont know how to fix it plees help me.

Is there a file with the same name already in the folder?

No there wasnt, But I managed to get the file there by simply dragging my file from its folder to the cdrom page. I didnt even use the ftp thing which makes me wonder what use it is.

Strange!
