Upgrade Information Not Available

I am using the free version but, I’d like to upgrade to allow storage on DropBox. However, every time I select the option to upgrade or buy a license, I end up on a blank screen. Please advise.

Hello,

To investigate this case we need more details. Could you please tell us what browser (name and version) do you use to upgrade your SQLBackupAndFTP?

Sorry for the inconvenience.
