Sims 3: 'No game disc found'

I've downloaded the 'Sims 3 complete collection' and successfully installed the base game, however upon adding several EPS; University Life, Pets, Ambitions, Outdoor Stuff/High End Stuff, I encountered the 'please enter University life disk, blahblahblah' error. I'm rrrreally confused and hopeless with all this tech-y stuff, surprised I even managed to get this far, haha. At this point I wish someone could dive into my PC and sort it all out for me.
Thanks so much!

Thanks so much for replying. I watched the video carefully but I kind of got lost after you installed 'Into The Future' ep. You clicked into supplements and started installing some manual patches, but I can't seem to find them anywhere.

Sorry, you can find all the downloads in the descriptions of the video. I just copied it below in case you are wondering, please let me know if you figured everything out or in case you need any further assistance

Yay! I re-installed the base game and put the ultimate fix crack into the origins Sims 3 game bin instead, and that worked! Thanks sooo much! x
