Thank You Warboy!
All saved games with MODs listed above load again perfectly. OpenXCOM is now as fun and addictive as Fallout 1/2 or Knight of the Chalice (tactical RPG akin to Champions of Krynn and Dark Sun)
The colorful, new, revolutionary AI, that is always showing new sides on every mission, especially in the Live Turns, (Quickloading the game seems to lessen the sharpness of the AI so a new "load only if half the squad is bombed to death - ""Ironman""-mode is the preferred awesome game mode now) and powerful new features and the promise of awesome MODs would probably make this XCOM a financial success if it went on sale on a theoretical market.
