RapidWeaver crashes when publishing. It also hangs when testing; doesn’t go anywhere! I have the latest version: version 8.
I think you’ll need to give us a bit more information in order to get some help.
There’s plenty of posts on the forum about publishing problems. There’s also this KB article on general publishing issues:

Again without more specifics it difficult to try and help. Does it hang on a specific task like preview, on a certain page or project, with a single plugin. There’s thousands of users that aren’t having this issue so there’s got to be something unique that’s causing the this problem.
