fix A couple of urgent ugly bugs
1. People constantly get that "Data not found" alert.  I can reproduce it is I try to navigate to a challenges page while the current page is still loading.  For example, quickly switch from design to development challenges.

2. On the My Account dropdown, the earnings are not showing. I think it may be missing from the API, so just put "n/a" for now.

3. On the profile page, the Member Since field is not showing correctly. It's always 1970...

If you can, please try to resolve these tonight.

Thanks,
Tony
