setup3.cab corrupted

hello all. i have searched the forum for both of these problems, but haven't found an answer.

i started trying to download the all-in-one. it took a long time and when i mounted it, i opened the disc and tried running the program. it would get a second or two into the opening and then crash. i don't believe this forum has support for the all-in-one, but just putting it out there if someone suggests using that.

so i began to download the .rar files for each expansion. the sims 4 base game completed, so i tried unzipping the file. setup3.cab and setup4.cab are both corrupted. when i go to install the game, the installation cannot complete because i need those two files. any advice?

i resolved this myself by uninstalling my torrenting software and installing another one, restarting the computer, and redownloading the zip!
