The crash likely caused it. Anyway, to fix the problem: open up an Athlete whose Home Page is configured the way you want it to be, then use the drop-down at the upper righthand corner of that workspace (for want of a better word) to "Make the current chart the default charts" or however it is phrased. After you do that, close this Athlete and open the one whose configuration went back to the default, and you should be back in business.
