I likewise have just downloaded LW Basic. It is not 100% straightforward... more like 99.99% -and is a tiny little bit naughty, but only a tiny bit!

Get Pro and Get Basic are big red buttons side by side Click get Basic and you just get a big red button saying Get Pro. Replacing Basic's red button is written "see below". While it does not take a degree in rocket science to see this, I can see that someone in a big hurry would assume that the Basic link did not work, but really they would have to be blind not to suss it out. As for popups ... no idea as I dissabled them ages ago, and if your browser doesn't dissable popups ....use one that does!
