I'm not going to bore you with my history of 25+ years of CAD program usage, but will say that Chief by far is the easiest one to use right out of the box (yes, we used to get a box with disks, manuals, certificates, etc., not like today with the ease of 'Download'). I looked into Softplan and compared it to Chief and found that Chief was just a better program.
There's a good tutorial on YouTube that goes through an entire project start to finish. It's a little over 1 hour but shows you a ton of the features.
I agree with Michael, it's time to jump ship. Good luck.
