I've been trying to get an answer on this in several places. Basically, I think that people for whom CGFE still works are people who have stopped their computers from updating. There is an idea over on FIFA Infinity that you can play in Win7 compatibility mode or use different bcrypt.dll file but none of that has worked for me. And the CGFE dev has moved on to PES. I think FIFA modding is done for anyone who has updated their computers until someone else decides to create a new tool for newer Windows versions.I can't open a mod in the explorer anymore too, when i try to open the Fifa Community Mod it takes like 1 hour to load, but then when it loads it gives that "splash" error as seen in a screenshot the user hixxx posted on the last page. I tried what regularcat replied to him but the error persists.
I'm using Windows 7 by the way, so i don't know if it's the same problem the Windows 10 users were saying about the update.
