Sorry for the late reply.
Please make sure first that you have enough execution time limit and memory limit. You can ask your host provider to change these for you. If you still wish to import manually, then please go to your wp-content\themes\tower\includes\dummy_data\backups folder. Unzip and import this folder: link. Now go to Tower > Import/Export (Dummy Data), select the backup and import it.
No it won’t. Don’t worry. The updates will only overwrite the theme files in your wp-content/themes folder. The data and settings you have already setup are saved in the database and therefore won’t be affected by any update.
I added this code: .top_nav .footer_social_icons.circle li a i { color: rgb(153, 153, 153) !important;} into your custom css box. The socials are visible now. They were already there in white color, that’s why you couldn’t see them.
