Multi panel saitek logiteck doesnt work on pc

I’m not a FS rookie, but I am 70 y/o who finds it difficult to work technical issues out myself. That’s why forum like this are great … and frankly put Zendesk to shame. Every big update brings a heap of problems that should be ironed out well before it appears as an update with all flags waving. I’m fed up of not being able to use the product for which I paid a lot of money.
