Solved. It was due to TubeHax denying the browser access to check if there was an update. First of all, sorry if this has already been covered, but I can't find any new source for help on browserhax 10.3 in the search, and the official site for browserhax doesn't say much. When trying to load browserhax, I get kicked out of the browser, with the usual "An error has occurred" message. I have put on the homebrew starter kit, put on the payload, initialized save data before usage, and even downloaded ropbin and otherapp for my version. What's going on?
