I just downloaded the one by WildArt from market, version 0.8.14.1. I got "Login failed" message after giving the id and password.
I have no idea what I might have missed in the process. After checking the detail of the app, it says the version (0.8.14.1) was expired at 9/30/10.
I don't know if it has anything to do with my problem. I looked into google group, the last report on the problem was dated in Feb, 2010 and it appeared it had been resolved.
Please help if you know what the trick is. My phone is a rooted D1.
