Upgrade from PRO to ULTIMATE

Hello,

I just upgrade my SmartFTP from PRO to UPGRATE.
No problem about the upgrade.

Where can I found my invoice (for my conpany) ?

After the paiement procedure, when i clicked on the "continue" button, i was redirected on a 404 page :

Please contact sales. They can send you an invoice or you can also get it directly from Plimus: http://home.plimus.com/ecommerce/shoppers/finding-order
