Hope you came right. If not, I had the same problem. No matter what I did, my carrier wouldn't show up, and everything kept on displaying free shipping. I re-created my carrier, I set all values to 0, I checked and re-checked my zones, country, ranges, product shipping.
Here's how it got fixed. When I loaded stock for my products, I selected the advanced stock system option, for which you have to define a "warehouse". You associate your "warehouse" with your created carrier, by going to Stock > Warehouse > and then editing your Warehouse. At the bottome, add all your carriers to the selected carriers block.
Once I did this, all my carriers showed up, my range pricing worked fine, and I completed by loading a payments module.
I hope this helps.
