Its probably a tuning problem, it takes a while to get good doing front derailleur setups. I doubt a 2009 setup has gone "bad" this quickly, probably just cable stretch.
Here are a couple of shots of the chain in the big ring, from the side and top. Sorry for the quality ... I had to hold the lever with one hand to get it to stay, while I took the picture with the other hand
Thanks
