Stuck on « fly » screen

After a flight which running perfectly, I returned to the main menu to change the plane and then was stuck on the « fly » screen unable to start any flight, from anywhere with the « Normal » mode or the « safe » mode.
When all the online data are « off », it works.
Has anyone heard of servers problems at this moment ?

looks like something with the servers. i hang on the boot screen and when the blue bar reaches the end there is nothing going on but the video card is 100 percent loaded
