Hoster: Go to
this link and purchase the upgrade. However, I'd suggest you wait about a week as we are getting ready to release Hoster 3.300.
Microstudio: Find your download email and click the download link in it. If you have lost your email, go to your
Account at our store and sign in. Then, find your order for Microstudio. At the bottom of the page you will find your download link, Registration Code and Email.
