[Theme Horse Support Team]

Hi hypergolica,
Copy the theme file in you PC that we have provided while you bought Clean Retina Pro theme. After doing backup your database from CPanel. Then delete the old version of your theme and install the fresh new version.
If you have not make any changes in core file of Clean Retina Pro than your data will not be lost. If you made any changes on the core file then all your customisation code will be lost.

All your settings will be saved in your database so you need not to worry while updating to new version but there should not be made any code customisation.

We cannot make automatic update functions because we only have once year of subscription.

Thank you!
