[Solved]FSPassengers became very buggy FS9

[Capt Flappers]

for years my FSP has worked flawlessly but now it is unusable. what happens is it will open but when i try to start a flight the green bar that shows aircraft fuel is not there, and the sliders for loading passengers/freight does not work, you can drag it to the right but then it goes right back to the left with 0 passengers loaded. all buttons appear selectable but the only one that works is "OK - Load Immediately" but no flight starts as there are no passengers or freight. the same thing happens in the "company manager" section, i can see company aircraft but the only 2 working options on that page are viewing aircraft and quitting the manager. the other buttons can be selected but the screen never changes from the company aircraft view. I am running windows 10 with all the updates. This happened several weeks ago and I tried uninstalling/reinstalling FSP using every imaginable combination of compatibility and run as administrator or not. I was able to get it working once installing without any compatibility selected, but it only worked for a few days and then back to the same issue and now it doesn't matter how many times i uninstall/reinstall or what compatibility i select the same issue is always there now. system is Windows 10 64 bit,  Intel core I5, 8 gb ram, 1 tb hard drive, nvidia geforce GTX 1050 Ti.0 graphics. Any suggestions appreciated, thanks
