Excellent plug in!!
Was working really nice but a little bug in my old version (0.2.9.4) made me to upgrade to 0.2.9.14.
Problem fixed, but now I can not add files from the front end. I get: "Unable to move file xxx! Is the upload directory writeable? xxx" It looks like the file is been uploaded in the .tmp directory but when to be moved to the right folder *ba-ta-boum*
Ftp works like a charm. Also front page widget for subscribers works like a charm which uses the same directory that front end tells me is not writeable.
Downloads & relevant permissions work fine. Try to tickle the .htaccess file a little bit, but doesn't seem to have any affect on it.
