Oil pressure too high

Hello, it has worked normally for four days and suddenly, any plane at the start of a mission (career mode) has too high oil pressure and the engine turns down. This has also happened in a certification I had started for turbopropeller.
So I basically can’t take-off in these modes any more.
I’ll be very thankful if someone knows how to proceed to sort this out.
Cheers
Ps: the same happens in league challenges in the race with the Extra 330LT
