There's no download button on the minecraft website?

I bought minecraft a while ago maybe a year, but my computer has been poopy lately so we reset it but i can't find the download button on the website when i sign in (when i say download button i meen the button that accualy has the download the "download minecraft HERE" button not the "DOWNLOAD" button on the main screen) so i can't download minecraft. And when I tried to download the launcher from a third party source it says that it can't cantact minecraft.net or something. I really want to play but I can't.
