Can't download additional substance painter assets after upgrading accout

I have downloaded 30 substance materials so far, not paying attention that there was a limit to how many you can dowload (new member). There are still a few more I need to download. but it says I need to "upgrade" to do so. I signed up for the additional service after clicking on upgrade yesterday, which I believe allows me to download 50 per month? anyway, after doing that, it still says that I need to upgrade. Am I doing something wrong? Thanks in advance,

Brian
