"patch required"

game says patch required; i click the button to close the game and apply the patch, and nothing happens.

Same here

The game stays at version 2.7.5.90101 and if I try the “Check for update” command, it says the game is up to date.

But if I start the game, it tells me it requires the latest update and closes …

Hi,

Looks like something is preventing the update for you… the current version is 2.7.6.91007
