I started Steam on May 3, 2022. I saw that Gen Zero had a short 3 min update. I went to play after the update, and the game would not load. Behind the game name on my Steam game list was this, “Generation Zero - Steam Cloud Error.” I emptied the game cache, and the Error still exists. I was able to launch the game from the game files but still cannot start the game from Steam. After starting the game a few times from the game files, I was able to start the game from the Steam game list like usual. The Error message still sits behind Gen. Zero. What is going on with the game? Please help. Steam does not know. Thank you.
It went away for me when I deleted the savegame and then started the game without it,
then copy the old savegame back in, that’s how it worked for me. IMPORTANT make a backup of the savegame beforehand.
