If you are on any version other than the Pro, then the upgrade is is available to you at 1/2 the price of the Pro Full license.
If you are already installed, all you need to do is purchase the upgrade from the http://shop.scoutingassistant.com
website. when you receive an email containing your upgrade license key. Perform the following.
Note: Assumes you have already installed and registered a "free" (or non pro) license.
Launch Scouting Assistant.
click Help | Register Product
Copy/paste the upgrade license key (starts with a "U") into the license key field.
Leave the Serial number empty.
Thats it. No need to download again. Keep in mind that the download/install is ALL versions. your license key unlocks the features applicable to that version. This is why you only have to install once.
Now when I come out with a new release I strongly advise you to download and install again to get the newest features (no need to uninstall)
Let me know if this is clearer.
Now if you just got a camera that comes with a free version, you can purchase the upgrade license but you MUST first register the free version BEFORE applying the upgrade license. It is two steps.
Upgrading should take 20 seconds once you receive the email with your new license key. also, remember that if you originally register using a camera serial number, do NOT input that when you are upgrading. Only input the upgrade license key.
