Seeing that b6 was out although unofficially, I've downloaded it, moved away my ~/Library/Application Support/TextMate, put the svn checkout of the latest bundles in /Library/Application Support/TextMate/ and...
nothing.
Lotsa beeps going on on startup and all files are showed using the language called 'Ruby on Rails' even though it is not a Rails project at all. Nothing is highlighted of course.
Any idea? I did re-checkout from svn as the path has changed.
