Thanks for helping to keep the price high until I can get my old coins out of cold storage. The wallet.dat file is incompatible with the new version so I am having a difficult time accessing them. Any ideas?
Besides my last suggestion of using pywallet there is another way of retrieving private keys using some old tools from 2011. There is a tutorial at this link, but it's only for wallets from 2011, not for later versions. That's why the first thing you read in the thread is a warning that it's out of date.
