Can you decode this file

Hi there,
can you please decode this file:

And also, would you mind to tell me how to use your decoder tool, if I decided to purchased it.

Thanks for your help.

Try this one, I reupload the files to dropbox

If the link is same, I assure you that this one the updated version.

By the way, if you can decode this, I need a bunch of it to decode, how do I use your service, and how your service works? Is your price apply per file or more than one? If I want to use your decoder to use it offline, how much do I have to pay for it?
