It says I dont have permission.
You must have done a naughty thing.
An admin/mod will be along to tell you specifically why.
Click the 'report post' button on you're original post and ask, if you're that antsy.
Thanks, No I didnt, and I did get a reply
"As far as I can see there's no reason why you shouldn't be able to get in there.
Perhaps one of the admins can shed some light on it."
If you don't get a reply within another 24 hours or so, just reply to the thread in the report section, or mark as "unfulfilled" if needed. All mods/admins are required by the Mod Gods to reply there, or they will be beaten.
