I'm trying really hard to not get upset.
So I have never heard of trying to install Exodus in the "My Documents" folder. I followed the instructions listed on the website provided. First trying the catalogue file test. It said that they weren't unpacking properly. I then uninstalled Exodus, reinstalling it to "My Documents" and got the attached error message when trying to start C3. DS works and the catalogue test said it was unpacking properly. I then re-read the instructions, uninstalled, reinstalled again, and got the same error message.
Now I don't know if I should be posting here at all as now the error isn't with the Garden Box, but the game install. I'm going to end this post here before I say something I'll regret. Good night, I'll deal with this tomorrow.
EDIT: Now that I'm a bit more level headed than last night, I think I found a passable solution. I uninstalled Exodus from "My Documents" and then reinstalled C3 Exodus to the default menu in Program files and reinstalled DS Exodus in "My Documents". C3 now works. DS also works and is unpacking agents properly AND can detect C3 too. I just reinstalled Garden Box and there was no errors. If I can keep straight where everything is installed then I'll be fine.
