Thanks again,
HERO:BTS and HERO:BitUSD both give me the same announcement. I'm sure i've tried correct markets.
My wife downloaded a web browser wallet (BitShares) a short while ago. It looks a bit different compered to one I'm using. It also seems that HERO-market should be working okey on that wallet. Maybe I have to get my own wallet's software updated. However, I've never done that and I feel myself unsure... Any hints or useful links to instructions would be a big help.
