hacker, I took a day break from the windlace and started on the passenger today. I sprayed the channel with liquid wrench spray lube and I found that the winblace slid much easier than when I used soap. Then the parts that didn't catch I just pushed in with a screw driver. Hope this may help you.
I have taken a few weeks break from the windlace after I got one side in,I also saw somewhere a note about putting headliner in first...good excuse to not install driver's side yet.
most of my windlace doesn't come near door
