I need help with smart card reader and a laptop.

So I bought a smart card reader yesterday. On the first website I tried to use it, it gave me a message that I had to change the settings, or some other options, or restart the computer. So I just restarted the computer. Now when I go back it allows me to select a user and enter my pin # for verification. But once I enter the pin it tells me that “your smart card is blocked”. I know my card has not been blocked.

Are there settings that need to be changed? I don’t know a whole lot about computers so any help would be greatly appreciated!
