I just Down Loaded Honest Hearts where do I go or who do I talk to to start it?

Head to the northern passage which should be activated on your pip boy...granted if you havent discovered the passage yet you will have to walk there...now the blockage should be cleared and you should be able to access a cave up the walk way there.

just found it but its blocked. when i check my DLC honest Hearts is listed

i'm disappointed i cat just start it like the other DLC's, no radio signal, no nothing

Did you get a Message Box saying Honest Hearts was loaded? If so, then it should be working-- if not, I would guess either it's not loaded, your Download was corrupt, or (if you're on PC) a Mod has somehow broken it (although I can't see the chances of that being very high...)

I fixed it, i didnt check it off on the Datafile options.

still not working is there something you have to do to start HH?

Not that I did... Did you get the message? If so, you may just have to leave the area, wait three days, and come back-- it's possible if you're there it has dirtied the save a little.

If you didn't, the best I can suggest personally is deleting the DL, and re-downloading it -- are you sure you are all patched up to date, too?

got it from steam, steam auto patches it self constantly

uninstall the DLC and and install it again maigth work

maybe i have to start a new game?

the DLC is there, it should work

i went into steam and tried to validate the fallout new vegas files and it found an error on one file so now its downloading the file now
