Hi, I am having a problem downloading.

1. The Mirror : 1
2. Your OS : Windows XP
3. The browser you are using : Firefox
4. Have you tested on a different browser? Yes, same problem
5. Have you read our FAQ problem or searched our forum? Yes, but there isn't any answer.
6. Are you using a download manager? I don't know what is it, so it must be "no"
7. The file/series you are downloading from. I'm downloading "Love Monster, chap. 59"
8. The EXACT problem! I can easily download the chap 58, but when i tried to download the chap. 59, i can't because of an "error 403". But I'm a member. So what can't I have the access to the download page ?
9. Have you tried right clicking the file and pressing "save target as"? Yes; I have download a "get_file.php" but i can't open it. so...
