Why psse turn off every time I try to run dynamic simulation !..?
HI friends. need your help  I'm in a serious problem, and I'm just a beginner with psse 
every time I want to run dynamic simulation the psse stops working and restarts, without returning any message, but sometimes after initializing there is no access to run bottom caused by initial conditions suspect 
The steps that i follow before simulation are : (please correct me if i missed some things ) 
1.  CONL ALL
2.  100 0
3.   0 100
4.   1
5.   CONG
6.   ORDR
7.   FACT
8.   TYSL ( until number of iterations is 1)
I read somewhere people talking about START activity  it has any relation with that ?.
Thank you in advance 

 
What version of windows and PSSE.
Win7 psse v33
