Can't restore current build, days of work lost

So, I dowloaded Unity's new particle pack, and for some reason that pack replaces all your tags and layers in your current project (who thought that was a good idea?)
So I went back to an old version to screenshot all my tags and layers.

When I then try to go back to (restore) the build containing the new particle systems, it just fails. I even tried creating a new folder and importing my entire project, took about 30 min to download the 25 000 files, and then when it finished it just said like "Error restoring entry", and the whole project was empty...

Literally all it says is "An Error Occured". Ok, great, thanks...

lost all motivation to work on my project now that I have to re-do days of work

 

Edit: Now it just says "Unknown error. Unable to use cloud services"

 

Server might be down. Just wait a few hours and notify unity.

 

Nah that wasnt it. just didnt work. had to re-do a bunch of stuff. Gonna start using Git, dont trust Unity's stuff anymore.
