Over the years, I’ve installed each new band in box over the existing version as well as any additional add-ons that I have purchased.
What happens to those add-ones if I choose to run band in the box from that external ssd ?
When we ship out hard drives or SSD's, these contain only the new BIAB version you purchased. Any add-ons, past or present, are a download only.
As Matt mentioned, you should be able to log into your account and download your past add-ons. If for some reason you can't find the downloads there, feel free to contact us and we'll look into it.
