Too bad this didn't work for me.
I spent 3 days trying to get the Microsoft store verison to work. I got it to work for ONE day, then when I tried to boot up the game the next day. The launcher refused to work.
The Tweaker fixed the issues with launching the game, but created an issue where I get the "Memory Error" when I attempt to login to any character on any ship.
I've tried updating Windows, DirectX, playing with settings, and making sure that Graphics card was up to date. Nothing his worked. I've spent almost a week trying...
EDIT: After uninstalling and reinstalling 5 times. I've finally had some success with getting the game to play consistently with the MS store verison.
