How to download attached file?

I have just installed the Payment form. Seems like a powerful extensions, but I have some small issues..
First is, how to download attached file? I am not getting any email with the file (just getting the text).
When I go to Payments management, and click on the file there, I get this error message (using Safari on Mac):
The most recent request was denied because it contained an invalid security token. Please refresh the page and try again.

The other issue is that the users are not getting back to the site after paying with Paypal.

Please can you help me with this?

p.s. Is there possibility to pay with Visa or Master Card? Can I use Paypal for that without having their account.

Thanks in advance,
Ado

Hi Ado

At the moment, the system doesn't send the attachment via emails. You will need to access to back-end of Payment Form, access to Payment Record to download the attachment. If you receive the error message when trying to download, there must be something on your site causing this issue, please submit a support ticket sending me administrator and FTP account of your site so that I can check and solve it for you.
