Can't find my purchase

I just purchased this theme. The money has been deducted from my account through PayPal and I have checked my bank account and it has confirmed this. However when I went back to my purchases to view it, there was nothing there. Does it take a while to update or may I know any reasons as to why it is not there as I need to start working on this website as soon as possible therefore a quick response would be appreciated.

Thanks,
Andrew
