Just re-bought KOF XIII on GoG to get a little bit further rid of Steam (and support a bit more SNK work), and after installation, everytime I try to launch the game, Galaxy tries to synchronize saves with the cloud (I never launched the gog version before) and it is just stucked on this forever.

Of course without galaxy the game starts and run fine (and the old Steam save is still there), but galaxy seems to hang on something about the cloud.

edit : apparently I had to kill the "galaxycommunication" thread which was still hanging after closing galaxy. After what KOF XIII finally ran.
