Update from me. I can login even I did not reconfigure anything, so the login issue was possibly just the waze servers issue. The problem is that altough I can connect with some permanent account I created before I am still having two issues:

1. no network connection, no maps
2. even I am able to login to Waze on N900 this registration seems to be not working for world.waze.com or www.waze.com, so I have no idea where my registration was done. Lost password option does not work on these servers, it respond with error that my e-mail is not in database.

Strange...

EDIT:
Tried the new config file as suggested damagedspline and got to the same point as some others. Login with my account is causing the freeze, New user->Skip will show return me to the login choice screen. So far no progress

When I tried to check what the hell is Waze doing with old "working" config I seen only very short connection attempt (possibly the login):
79.125.19.110:443 CLOSE_WAIT 4199/waze
After that I did not seens any network communication. So I tried to login with temp. account aaaaaand from some strange reason I seen the map and some message, then the Waze crashed. Tried to restart, seen the message that Waze haze crashed (surprise) and question if I want to send report, click Yes, crash again...
