Pop Up Ads

I installed X4 on my home PC.  It's the last version I purchased for personal use.  Every single time I launch the program, it pops up an advertisement to upgrade to X8.  There's no way to prevent this from happening.  It's exactly the same behavior as Microsoft is doing with Windows 10 and it's terrible.  I'm never going to buy X8 and this is wrong for them to treat people this way after they've already bought the product.
