We have released a Mac app update to Apple to address the issue of 10.7 users updating their database, and to hopefully fix more 10.7 bugs. Please note that we still recommend you to upgrade to Mavericks if you can, as we will be dropping 10.7 support soon.
We have also taken the opportunity to add in Card Shark price charts, so that you can quickly see the recent price history of a card. Check out the screenshot below!
