Hello. Can anyone answer my question?

I went to buy the Pro version of LimeWire for my Mac OSX, but on the web page where I have to put in my credit card details there is no 'Padlock' icon in my browser. I use Safari but I also looked at the page through Internet Explorer but with still no luck.

Is it just that the page is insecure? If so, then is there a secure place where I can pay for the upgrade?

I've heard good things about the Pro version, so if someone can help me out here then that would be well good.

Cheers.
