Hi guys,

 i bought the game about 2 or 3 years ago. Now i just reinstalled it and wanted to try some online multiplayer. I guess i have to update to the newest version, right? So i clicked the download updates button within the game which brought me to "https://www.sinsofasolarempire.com/update". There is stated that i have to register the game within stardock. Luckily i kept the manual of the game on which the serial is printed. But when entering that serial in stardock it says "Invalid serial". Maybe the serial is to old? So what else can i do to enjoy some online gameplay?

Info: I bought the original game (no trinity or entrenchment)
