About the NW thing, it's not from your side but the server's, it often makes people crash right after getting inside but since you can only get one pass, if you end up in FB51 you can't get back unless you PM a GM to teleport you. It helped some people to wait a bit after NW started (since so many enter at the same time once it opens) and then enter.
The TM bug is also quite frequent, the only thing I've heard of was that people had some old TM quest in their quest log making them crash, if this is not the case for you then I'm not sure. It's something Agatio would have to fix but I'm not sure if he has any way to at the moment.
