Download Problem Pro Version

I just bought the standard premium package from “portfoliolpugin” from miixee and I can’t download the order, if I click the button, there always comes this message:
Oops!!! The transaction id is missing in our records. If you think something is wrong, contact us here < [email protected] >.
