Hello Littlepe,
Thanks for the Dxdiag. I observe that the processor, RAM and OS are quite suitable. However, the graphics card is not in conformity with the System Requirements. SSE requires the Geforce 8800 GT as a minimum and its current ranking is 114. Your Geforce G210 is ranked at 486 which is way below.
SSE is a very 'graphics intense' simulator and need a graphics card that can take the load. It could be for this reason that the conning compass looks different. If you are considering replacing your graphics card now, please also give great emphasis to the PSU (power supply unit). A low powered PSU will damage the card beyond repair. The specs of the card will also mention the wattage of the PSU it requires.
