Sims 2 installation problems

I got the Sims 2 game for Christmas with almost all of the expansion packs. I am running Windows 10. When I download my Sims 2 game, it works perfectly fine, but when I add an expansion pack/stuff pack, everything goes wrong. I tried installing the Kitchen and Bath interior design stuff pack, and after installation I was asked to reinsert my main Sims 2 disc, which I did, which would result in an error stating 'TS2UPDO.exe has stopped working.' After a lot of research and trying many different things out, I managed to get it installed by restarting my computer instead of inserting the Sims 2 disc. However, once I did this, now my game doesn't work. I can open it and the menu is perfectly fine, but if I try to enter create a family or click on a lot to play, it simply stays on the loading screen and will not load. I don't know if this is to do with my restarting of the laptop or something else. Every other discussion of this has suggested deleting custom content, however I have none and haven't done any sort of gameplay. I have also attempted to install Sims 2 patches but it results in an error. I have no idea what to do, and I feel awful as quite a lot of money was spent on this present. Does anyone have any ideas on how to fix this? Thank you. I have attempted installing and reinstalling multiple times.
