2.5 not working

I have a quick question, SmartFTP 2.5 no longer works on my computer for some reason. When I try to start it, it just gives me an expiration notice, that it is about to expire. I hit 'ok' and nothing happens. I do not wish to use SmartFTP 3.0 because honestly, it can't compare to 2.5. Thank you.

I found a way around it, thanks though.
