Desparate to be able to correct my "Media directory url:" in "FILE HANDLING/FILE LOCATIONS"

Hallo graciousnessessss,
Am I really screwed that my path to files in SWFTools configuration is permanently wrong and can't be corrected? It's grayed out in FILE HANDLING.
I'm using module FLASH NODE with SWFTools and while "importing flash" files, it stopped at my incorrect relative path to my private files directory. (I have lots of large flash videos I'm ftp'ing then flash node publishing. First time at this stuff....)

"The import function will scan the /hivetools/../hivefiles/flash directory and sub-directories to locate files for import.
No files were found for import."

I don't think the config.php fix will work, because my files are not publicly accessible. Correct?

"This helps swftools identify the server where your media files are located. You cannot change it here, as changing it has the potential to break existing content. You can set this on the $conf array in your settings.php file. For example:

$conf = array(
'swftools_media_url' => 'http://anothersite.com/media', // No trailing slashes!
);
Leaving this value unset in your settings.php file will persuade SWF Tools to check for the existence of your media files, as they are automatically assumed to be on the local server."

How can I change it? I don't think I'll break anything, since this is all new. I just messed up the path.

THANKS MUCH!
