It appears as though the site has moved to forums.soldat.pl.
A large number of the links in the Need Help? section pointed to forums.soldat.pl, which still works, however the site stores the cookie for forums.soldat.pl, so when a link takes you to forums.soldat.pl the cookie fails to register you as being logged in. It also seems to be impossible to sign in and remain signed in at forums.soldat.pl.
I've gone through and fixed most of the links that point to forums.soldat.pl in the Need Help section, but I'm wondering if there's any way to fix this issue without editing three dozen posts or more in each section.
