Thank you @Goodywood :) It was definitely a process! I was really nervous about getting started, at first, but it had to be done if I wanted to play with the items that I earned/was gifted. I was afraid that I'd mess something up, but once you're done with one ebc file and it's at the right size, it's done. Rename it, move it out then move on to the next. :D I had to restart a couple of ebc files because I messed something up, but that was ok. At least I know what goes in there and it's not like I'm having to reinstall everything, just what's in that one file. ;) I wish you all the best with your install.
@ciane thank you, I'm looking forward to playing with my new stuff! :D I have an all disc install, but was forced to 1.69 because my base game was newer. My daughter found a used pre 2012 disc on EBay for $2 so if I want to detach from Origin I have that option.
