It seems that the rgss2a file is corrupt. The game itself can't open this special file, which is why you(and all others who are trying to download your files) get this error:
サキュバスメイズ

アーカイブの読み込みに失敗しました。

OK
Could you try to redownload the most recent version?
Make sure that you are extracting the files while your system is running with the japanese unicode.
Make sure that the DRM thing is finished, before you copy the files someplace else. When you are able to see the Start, Load and End Game Buttons(The Main Menu), that's the moment where you can copy and upload the files.
Here is an easy to use Decrypter for the rgss** files.
You must be registered to see the links
Yes, it's an executable file, so its not the safest thing on the Internet. However, I've been using this file for over a Year now and nothing happend, so I'm pretty damn sure its safe.
Anyways, start the decrypter and open the rgss2a file. (First Tab "File", then "Open File"). If its not able to open the file, then the rgss2a file itself is corrupt.
If the program is able to open the file, then everythings good. Just extract all the files(Second Tab "Tools, then "Extract All Files")
Look for the folder named Extract, it should be in the same location where the decrypter is. Just Copy and paste all of the folders from that one into the main game folder.
After you decrypted the rgss2a file, and copied the extracted files into the right location, make sure to move the rgss2a file somewhere else. Next Time you open the game, it will notice that it does not need to check the archive for the game files since they are already there. That should take care of almost any problem.
It's a bit of a long explanation, but I tried to keep it as easy as possible.
Still, thank you for your upload. It does not work, but its good to see that you are willing to share with us.
