Is it the whole group or just a certain forum, or what? If it's just a certain forum within a group, a lot of groups have an admin only forum where they can discuss things, or look over controversial posts or whatever. If it's a whole group, and it's saying you're not a member, then you need to reapply or something - you were too inactive to stay a member. If it says you're blocked or something, that means groups admins blocked you from the group for one reason or another. Your best bet would be to message the group owner and ask what the deal is.
