Hello there i have played SC:remasterd later today untill that error come up and i can’t fix it. "StarCraft encountered bad game data that must be repaired . " . I did run repair and also try this that found on some topic:
" 1. Press windows key + R > Type %programdata% > Click OK > Delete the Battle.net and Blizzard Entertainment folders
2. Press windows key + R > Type %appdata% > Click OK > Delete the Battle.net folder
3. Press windows key + R > Type %localappdata% > Click OK > Delete the battle.net and Blizzard Entertainment folders
Once done start up the Battle.net App again and try to Repair the game once more. This should fix your issue."
But still error is poping up again.
