[TSL/14] - SylvanSpider35

So my friend can't log into the truckers MP (game, website is fine), I just finished helping him install it and no matter what we try the game always says "invalid Email/Unsername". My first response was to come to the forum, and I found a similar post someone made with the exact same problem and we tried every solution that every person gave (moderator, member, and support) but nothing worked.
