Can't Upload For Product Download

Hi!

I’ve just installed this plugin, and I want to sell an MP3. This file uploads without problems if I do it directly in the Media Library.

However if I create a product and then upload it via the Product Download section, it fails with this error message (stars added for security):

Warning: filesize(): stat failed for /homepages/31/d*****4/htdocs/wp-content/uploads/wpsc/downloadables/musicfile.mp3 in /homepages/31/d*****4/htdocs/wp-content/plugins/wp-e-commerce/wpsc-includes/form-display.functions.php on line 93

If I try and select an existing file it simply shows nothing there.

Similar issues on here have been reported and users have been advised to deactive NextGen, however I don’t have that installed. Actually, I deactivated all plugins and went back to the default theme, but still the problem was there.

Any ideas please? This is quite urgent as the product was meant to be available for Christmas 🙁

Thanks!
Matt
