SmartFTP Won't Open on Windows Vista

For some reason SmartFTP won't open on Windows Vista. It will go the "buy full version" window, but then when I click out of that it just doesn't do anything. There is no SmartFTP process running either after.


Whats wrong? I'm sure this is a common problem because it has now happened on two computers. Unfortunately I couldn't find the answer to my question on the forums.

There is no upgrade available for this version. It is the latest. And we are supposed to be able to use an unlicensed version for non-commercial use. Read your website.


What does the dialog say?
Either upgrade to the latest version or purchase a license. These are your options.
