Maybe it was because I did something different..? Here is what I did:
-Cleaned the broken tab with a powered wire wheel to get a nice clean solder/shiny metal surface. A piece of sandpaper would probably do the same job.
-Cleaned both the tab and the spot on the rear window where it goes with Mineral Spirits as I had no "alcohol" handy as the directions suggested.
-Soaked the tab with the activator, and let it sit.
-While I waited, I kneaded the copper adhesive until it was completely mixed while waiting almost 5 mins for the activator. I probably did not wait the full 5 minutes for the activator to dry.
-I put a good size blob of adhesive on the window, and kind of mashed it into the spot with the edge of the tube, as it is a bit runny.
-Pressed the tab, very very firmly into the goo, and held it for over a minute.
-Went back later, and saw the goo had run down the glass a bit, and was surprised it was not solid, so I wiped up the drip, and was pleasantly surprised the tab was pretty solid. I did not test HOW strong yet.
-Went about other projects, and a few hours later, I attached the wire.
-This morning I tired the defroster, and to my surprise, it worked. Hopefully it will continue to work.
For the under $10 this costs, it was worth the gamble for me.
The original tab is stuck in place with the same material that comprises the defroster lines: sintered metal. It's applied hot, as a spray and just sticks to itself. You can't duplicate that process.
I tried other methods to fix this problem:
I tried to solder it back on, but no combination of flux (either acid or rosin) would make any variation of solder stick (electrical, silver, lead-free, cold). You can't heat that large of an area up enough to make a good bond, without doing damage to the glass.
I even tried to mix fine copper dust with JB Weld steel epoxy. I kept the layer between the tab and the glass as thin as possible to keep the resistance to a minimum. I then layered more on top and around the area to keep it steady. It seemed to work OK for a while and it didn't break off. Until I started it remotely one day for about 15 minutes. When I got in I panicked because I smelled the distinct smell of burning-wire smoke. The epoxy had burned and smoldered. Thank goodness it didn't start a fire.
Feel free to try this stuff, but I suggest consulting a professional for repair or replacement. It's not something you should screw with yourself. The results could be bad.
