bimmer,
you have 3 options:
1. go into the ditor and increase resource appereance of coal, rubber, aluminum, uranium and oil by about 10 to 20% each.
2. learn to play far more peacefully thus increasing the chances that through diplomacy and trade you will still have acess to resources that are not within your empire (switzerland style). learn to play far more aggressively, without any qualms about taking by force whatever you lack (totalitarian style).
3. throw the game in the trash.
I reccomend number 2.
