Okay so I found the digibyte.conf file in the folder where I exctracted the .zip. The only addnode that wasn't already there was the one you posted earlier. I added it but I still have only one connection. Also I noticed that content in that file is different from the suggested content in that first post you linked. Should I use the config from that post? Thanks for helping me!
Getting the conf from the OP wouldn't hurt to try again. I haven't had an issue since launch and I'm still running the same list of nodes. (a few added that aren't in the OP actually.)
rpcuser=youruser

Here's mine if it helps.
