Problem with new version of Mission Planner during startup 1.3.8424.42890

After update to newest version of Mission Planner 1.3.8424.42890 I get 2 error messages

. Updated to newest beta still the same problem.

That same Beta Build version is working for me.

Older versions were working without problems…I checked on another PC lapotop installed without problems. What I have to delete to do fresh install of MP ? Any files in other folders than in Program files ?

Ok I had to delete files in folders Mission Planner in “Documents” and in “ProgramData” and install the program again and now it’s working…
