This is so very sad. Ive been paying a lot of money for my hobby. Not to be an technician.
When I buy stuff I fully expect the items to work properly.
Its upp to you to test and make shure everything works as intended.
And yes of course. Blending 3rd party freeware is cause a lot of issues.
But you should have known there might be some issues.
Neither SkyMaxxPro or XPRealistic is freeware.
I fully expect this to be solved very soon. Or ill reclaim my money.
Its a pity when the product in all is quite good.
