sims 4 Lumpinou mods

Am I the only one who cant use Lumpinou mods? I downloaded the most recent version of their Relationship & Pregnancy Overhaul and my entire game shut down. I had to actually uninstall and redownload the game. I for some reason tried to download the mod again and it had the same result. The RPO mod isn't the only one of their mods that this has happened with. I followed the rules for installation exactly as listed and downloaded any requirements they listed. Its gotten extremely frustrating and I'm starting to wonder if I should just give up on their mods. However the first impression mod is calling my name so if somebody could please help id really appreciate it.
