hi,

yes, it is possible to back up and restore all of your custom art materials in artrage.

I'm not sure what OS you're on, but assuming your current machine is still working and accessible, and you can run artrage at this time -

you can access the content folder by going to "tools" -> "browse content folder" -> "root contents folder". it will take you from artrage to windows explorer or mac finder, and you'll be able to duplicate it on your usb drive, or put it in the cloud.

when you create a back-up of this folder, just replace the content folder on the new laptop once you've installed artrage there and registered your serial number again. you should now have all your custom tools and settings plugged in and ready to work again.

you can technically back-up just stencils or just stickers or just brush presets selectively, but all of them are stored as the sub-folders of the content folder, so keeping that one preserved will cover all the customizations you've collected or created yourself.
