I'm basically in the same jam, I've been using an optimum wifi for roughly year and no problems, basically have been playing everyday since launch then about a week ago I got hit with this Marionberry error and I can't get in at all, I've also tried bungie's fixes along with other around the web to no avail. Everything else works fine; I'm able to access the online content of every game I have BUT Destiny and it's really infuriatingly even more as I've been getting invites to Raids. I hope this can be patched as I bought the LE along with the season pass, that'll be roughly $140 down the drain
