The Import Update Files item updates your local SuperService source files with the new month’s datapak from Infomedia. This is *usually* done for you by staff at ACS. If you are instructed to import your update files by ACS staff, simply goto Service -> Infomedia SuperService -> Import Update Files
Tick the box indicated and then click continue. Allow the update to run. The time taken to update the files will vary depending on the size of the update.
Note: There is no longer any need for you to download the update files from the internet as ACS now upload them to your server directly to minimise errors.
