TheoTown

Good afternoon all.
I'm a new user on a Windows 10 PC. I'm working in Sandbox mode and suddenly for some reason the icons for Entry and Gates show a padlock! Yesterday they were normal? I'd appreciate some help with this. Also how do I lay down a runway?
Thanks for letting me join the forum by the way.

Did you build a tower, then remove it? That would block the entry from being built. Same with the entry. If you built one then removed it, the gates would again be locked. The runway is placed just like a highway.

Thanks for the quick reply - yes I did remove a tower. But I uninstalled Theotown via Steam and then removed the folder in My Users. On re-installing it the problem was still there. I think I'm going to have to learn how to install and airport properly!
