FIFA 15 on PC suddenly won't start anymore, I have reinstalled the game, it can't repair and I have the product code for my game. When I open up FIFA 15 and press play the game starts loading for one second and then it crashes. EA Support couldn't help so they sent me here, what should I do and does anyone have the same problem?

I had the same problem, so here I go with what I did to solve this:Like kurtkorv said, I think everything is on Windows Defender.So, the first thing is to check Windows Defender on "Protection History." For some reason, it detects "dbdata.dll" in the FIFA 15 folder as a virus. If you can restore that file, do it. If for some reason you can't (as was my case), delete the game and reinstall it. (I restarted my PC just in case.)Then, go to Microsoft Defender again, go to "Threat Protection settings," then go to "Exclusions," and there select the folder where you installed FIFA.After I did that, I started the game, and it looked like it crashed again, but I left it for about 30 seconds to 1 minute, and out of nowhere, it started the game smoothly.Hope it helps, folks.
