@Goodywood even if you messed up the first ebc file, you can just redo it. That's the beauty of it! ;) Just know it'll be ok if you have a "do over".
I kept everything that goes into Downloads, DCBackup, DCCache and Library folders and put them into their own "backup folder". I did this one ebc folder at a time as not to get confused/overwhelmed. It was very slow going for me but that was ok.
On a side note, before I decided to install everything, I redirected my documents folder from my tiny SSD to my larger HDD. I think I mentioned this earlier in this thread.
Things really downloaded and installed fast on the HDD, but it took 8 minutes loading time to get into the game completely (not awful but 2.5 to 3 min for SSD) . I know it was rendering all that stuff for the first time so I'll take that into consideration. I'll see how it goes next time. :)
