Opening Layout files without Pro

Hi. I downloaded Sketchup to play around with a room’s floor plan. With the download, I was able to use Pro for 30 days for free.

Now that I do not have Pro, and do not want to purchase it, what programs can I use to open the layout file I have? I tried using the regular sketchup program, but it wouldn’t open it. If I try to open it, I get an error saying my Pro version is not licensed, even though I have uninstalled it.

I am working on a Mac.

Thanks!

LayOut files can only be opened by LayOut and of course that requires that you have a Pro license.
