i just do fight skirmish of deneb j-5 i think dont remumber the sector and when i jump there the loading takes so long then the game closed by it self then when i re join the game its stick on entering universe forever i waited 20 mins and nothing happend

I had the same problem - try dumping your plug ins and if you escape then avaoid that area... there are still a few loading issues with the dense sectors and any extra delay can cause this problem.
