If you have problems getting into the forum after the hack use this link: forum.livingsims.net
It should let you get in without any problems. If you still can’t get in you need to clean out you caches. How to do that is different in the browsers so google “clean caches [browsername]”
If you are having problems getting in please email livingsims[at]live.dk so we can help you out, or post here.
