My form got disabled, I am using the free one

Hello!

I'm using JotForm for about a month.. People are uploading files through my form. And today, I got an email saying that the form was disabled because of overquota. Please, help me! Do I have to buy JotForm subsciption in order to "revive" my form? I don't really want to spend my money right now :/ Is there any way to enable my form? I've already tried deleting some submissions.

Thanks in advance.

You must download all your submissions and file and then delete them, that's the only way to free the space up.
