Walt - If you look at the title of the web dialog it is saying "http error 0". Sorry about the confusion. I thought that it would be good to show the web dialog whether you have an error or not? I could change the back ground color from wheat to red or something like that.
The other thing to note is that you may need more accuracy than 1/2" precision to properly draw a stair case. I'm not exactly sure how sketchup handles smaller values than precision.
If you let the defaults.txt file to "User" and "test" and connected then you should see "Testing - temporary status granted"
If you edited defaults.txt file to "mwm5053" and put in the emailed password then you should see "You have 30 days left in trial"
