Its working!! I deleted all of the various versions and reinstalled the packages and now its working.
I think I did something wrong when I installed the new version. I noticed that when I asked it to install LibSDL2Design 1.3.3 it said it was also going to install the 1.3.1 versions of LibSDL2 and LibSDL2Extensions. So I deleted them all and started over and made sure it installed 1.3.3 of them all.
So, now I have some squares (and a rectangle, a triangle and polygon)... One of just 4 points, one two lines, another 3 lines, 4 lines, a triangle, a polygon and various blend methods. Is that correct? You said something about circles? Did you change that?
