Ok, i fully reinstalled the Game, patched it to version 6, use downgradepatch after i Run the Game 2 times and KEEP Online! deleted the Xcom Folder under "my documents" and try to Run it after downgrade.. First Time the the same problem, .exe in the Taskmanager, but nothing happen... Shuttle down the task and try it again. Now the install window appears and after that (Steam is online after all) it start the Game! .. well .. fine, so i install the Mod "Long War" and go in the Offline Mode... again the Problem: . exe in task, but no Game start. What did i wrong?!?! (Sry for my bad english, ;) )
