So, I just commented the "Content-length" header string in attachment.php:

header('Content-Length: ' . (($lastbyte + 1) - $startbyte));

And now it's works, but I think author should fix this problem in his product. Thx. = )

This mod is not supported and last update was about 19 months ago. I wouldn't look for an update, but your post is valuable to others with the same problem.
