store manager

hi i cant seem to back up my store anymore thsi is what i get

Error when downloading file ! Ftp server response: Downloading file failed: Can’t open //files/ No such file or directory

Download '/
/backup/files/’ to 'C:/
/ Manager 2.0/local/backup/**************.zip’…


Script '/backup/backup.php?mode=files&password=
&action=continue’ ends without errors

Script '/backup/backup.php?mode=files&password=
&action=continue’ starts executing …


Run script …

any one have any ideas???

Store manager 2.04 returns exactly the same message (backup DB)

I checked with ftp : Files does not exist in directory (was not created by script?)
