Hello MintDrake,

Wild mode packs are locked until you reach the rank bronze 10.

About the install/update on your computer, it’s probably caused by another program, this article should be enough to solve your problem :

Some programs can still cause problems, even when deactivated. You should temporaily uninstall any anti-virus, proxy etc that could hinder the install. Else, you can circumvent the problem copy/pasting the game from another computer.

About the lost progress, you’re apparently not connecting the right account. Please make sure to use the right email when connecting to the Battle.net app.
