Hey @Nikki!
I had a look at Carbonite and saw that it only supports macOS and Windows, unfortunately. One good solution that has come to my attention, if you need Cloud Backup, is IceDrive (www.icedrive.net). There is also the IDrive, which can be quite cheap to begin with, but I found myself not having access to my files for 5 days straight before someone got back to me from their support. Naturally, there are also the local options, at which Linux excels.
On the HP side, I’ve successfully installed several Linux distributions on 3 different HP laptops, so the OS works nicely there.
Per your LMS issue, what @dennis said is true. You can either contact support@jeff.pro (this includes subscriptions), but if you have simple account issues, just as you have, you can Private-Message me here too. To do that, just click on my name in the forum and select Message. All I’ll need is the email address you registered with and I can check it out for you.
