Hmmm, I will try and walk you through the problems as best as I can.
So I downloaded the file (was I supposed to just right-click and save it from the website?). I tried to use Rafiki again, but had the exact same error. So opened up the playermanager.sei file and noticed that it said "<!-- saved from url=(0062)
https://dl.dropboxusercontent.com/u/...yerManager.sei -->"
Is that a problem at all? I'm also a little confused on how to differentiate between a text and a SEI file. If this is a TortoiseSVN problem I can fix it, but I really am not sure where to start.
Last problem is that I opened Simba back up and the SLR menu is not there, even after I checked it in extensions again, so thus I cannot open Rafiki to even try it. I also re-downloaded Simba and reset everything and the same exact thing happened. Sorry for all the questions, I am just trying to be as clear as possible.
Thank you for being so helpful so far!
