I'm having the EXACT same problem here. I don't know how many other people are having this problem, but I hope it gets fixed. All other sites with Votifier compatibility seem to work just fine for me, except for PMC. I only have two listeners; FlatfileVoteListener and Vote4CashListener. I have checked multiple times to be sure my key is identical on both ends and I have tried looking into everything to fix this, but it just doesn't seem to work. I want to post this because I really want this bumped back up to the top of the forums. It seems to be at least somewhat of a common issue.
