A bit of context here, my laptop got in a really bad shape since I came back from BronyCon and well let's just say I only managed to open back MLK correctly yesterday. Thing is, I can't send any scores, as I get the "Error Login!" message. My user is still in the game and logged on the leaderboards, even if all scores are gone on local along with a few songs. And it's not the player name, I made sure it was not a default one.
Here's the error log, seems to have something to do with a "mlkhs.dll" file

Also hai, it's been a while.
