To upgrade your Sytist, log into your PicturesPro.com account and view your order that you purchased Sytist on.
Click the download link for Sytist and save the zip file to your computer. Unzip the zip file to a place where you can find it.
The upgrade files are located in the sytist_UPGRADE_files folder. Do NOT use the installation files.
Connect to your website with your FTP program.
Navigate into the folder where you have your Sytist files located (public_html possibly). You should see existing files and folders with the sy- prefix.
Select the files and folders from INSIDE the sytist_UPGRADE_files folder upload them INTO your folder on your website OVERWRITING the existing ones.
NOTE: If you admin folder is named something other than "sy-admin", you will need to upload the contents of the sy-admin folder INTO your admin folder.
After the files have completely uploaded, go to your Sytist admin and it will automatically complete the upgrade. You should notice your current version will change to the new version.
