Download quota has been exceeded.

Hello,

Currently I am trying to test the Planet API (I am still on trial period). I quick searched as shown in the documentation. Then checked the assets of the specific feature. It was inactive, I tried to activate it with the provided link, however I got the following response:

{
    "general": [
        {
            "message": "Download quota has been exceeded."
        }
    ],
    "field": {}
}
