I had the same problem today - over 6 hours and the listing still hadn't showed. I contacted Ebay via live help and put in a complaint about Ebay discriminating against Auctiva users and hey presto - my listing showed up immediately! Note..when using Turbo Lister my listings show up immediately. I've not yet had one go up straight away with Auctiva. I suggest you put in a complaint to Ebay if it keeps happening.
