Campaign crash upon loading

[Jakoporeeno]

I installed Roma Surrectum 3 for Steam as according to this tutorial (https://www.youtube.com/watch?v=FNOhyGx2NhQ&t=2s) and haven't gotten to play a campaign yet. After I've moved all the Roma Surrectum content into Rome Total War Gold and chosen a faction in the launcher I try to start a campaign. If I start using the RomeTW-ALX.exe I get the "please select an item from the list" sign, whether I choose to start a campaign as RTW or Barbarian Invasion or Alexander. When I try to start a campaign as RomeTW.exe I don't get the sign but when I load the campaign map the game crashes. Please help. I bought Alexander pretty much to play this mod. I'm using Windows 10
