I feel like I’ve become stupid. Auto-translated

Hi everyone, I decided to fill my map folder with different maps today. I downloaded a bunch, added them, and nothing happened. Version 3.1, so I thought maybe I missed something, checked everything I downloaded, but it didn't help. Okay, I downloaded the game again from somewhere else, stuffed it with maps/scenarios/campaigns... and still nothing happened. I did everything as usual. In short, I've been messing around for 3 hours, and the cats have already started swearing =(. I'm ready to delete everything and reinstall. The question is, where can I get a new copy now, or where can I buy it so that it works without any problems, once and for all.

You need to place each map individually into the "maps" folder and then play it. After playing, delete it and load the next one. If there are too many maps, they might conflict with each other, causing the game not to launch, or resulting in glitches and crashes.

Oh, I haven't tried that, thanks!
