Can't Open SmartFTP

I tried double clicking on the SmartFTP icon on my desktop (the box that says my SmartFTP is about to expire pops up, I click ok, like I always do, but then it dosn't open, and i tried a bunch of times in a row doing this, because sometimes my old smartftp would take a couple of times, but nothing!). I also tried going from the start menu and the programs menu but it won't open. Again, the box that asks me if i want to upgrade pops up, i click "ok", but then nothing, it doesn't open... Any thoughts? Any ideas on what good temporary FTP program would be, until i figure out what the problem is here?

Install SmartFTP from:
[url="https://www.smartftp.com/download"]https://www.smartftp.com/download[/url]

We don't know why the MSI setup doesn't copy the new files for some users.
