You may want to have your preview images link to your website, for me it's rather annoying to type your website manually, and as we all know, people tend to be lazy.
I do have to say that your new website looks better than before, although the color theme isn't for me, just personal taste though.
But it seems it's not quite finished yet, looking at the Features page, which is completely empty for me. You may also want to remove the arrows in the navigation on links that do not actually have a dropdown such as News, Features and Register.
The registration form isn't quite tab friendly, it takes 3 tab hits to get from password to email, just a small improvement but that's what I noticed.
Secret questions are in German while everything else is in English, same as the server rules, not sure if it works on locale basis, but also something worth looking into.
The Signup Script gives you a pretty bad response, it took me forever to reload the page and it just gives you another text at the top of the form that doesn't catch your attention and just shows you the signup form again. Had to look for the actual result.
For downloads, you may want to open the links in a new tab, just to not interrupt browsing experience if people first download then want to sign up.
The "Impressum" link, first off, is in German again, and links to nothing for me besides the current page. Could be an issue with a .de domain.
Twitter and Instagram links also do nothing, so why have them there?
Accessing the account panel also feels off, having a modal pop up when clicking on "User Panel" and just having a small button to get to the actual panel.
I'm also not sure why, but logging back in after logging out also takes forever.
The shop only has items in 1 category, also kind of weird to have it like that. At least output something like "No items in this category" or just don't show the category then in the first place.
[Haven't taken a look at ingame yet, but might do later.]
Good luck with your relaunch, hope the bits of feedback helped.
