Firmware 9.00 All rides set to today

After having finished my ride yesterday the unit (Edge 1030) Froze. When I finally got in contact with it again it started a VERY long beep that I stopped by pressing the power button for 10 sec.

After that it came on again but now the time for all the previous rides was set to Today.

The same happened today again and this time I couldn't upload the ride with Garmin Express.

Have a nice day
