Do Premium Membership's automatically charge you for another month when your subscription is up? If not, then I am concerned as to why i was billed for another month subscription when I did not subscribe. Also, the banner adds still exist, so the only benefit i'm getting is this forum.
Check this thread concerning your auto charging concerns
As far as the ads, not sure what could be the problem. :think:
As for the banner ads, log off the site, clear your cookies/cache and log back in - that should fix the ads.
Right...or hold down Shift and hit Refresh/Reload.
