Can't run SmartFTP

I have just upgraded my product and I can't get into it....try to activate it which should be done with my license key which is on my computer...so I run that and it still will not open...just says buy or activate and no trial days left.

I can't get technical support because I can't open it to go from the help section.

Thanks in advance
