Hello Gabriela!

WebSite X5 Evolution 8 and Website X5 Evolution 9 are compatible therefore, you can import your evo 8 project in your new evo 9. The programs work in two different ways therefore you might have to adjust something in your evo 9 project but it will work.
if you wish, please feel free to have a look at this Tips&Tricks document that can help during this process http://answers.websitex5.com/post/4591

You can purchase the program from Argentina on our store: http://www.websitex5.com/en/store.html If you purchase the download version, you will receive the program as soon as we have received your payment.
