Lol, I told you you could reinstall it with bannerbomb. No need to re-mod. So yes I did answer that question.
I can't tell you what happened to your HBC as I don't know. If it was deleted by the update you would be the very first person and I have already accepted the update you have and nothing bad happened. Everything works flawlessly.
Use wad manager 1.7 and IOS36 or IOS236 and see if it makes a difference for the ret 1 error. That is the only advice I have.
