WD won't start

For no apparent reason WD won’t start. I get the following message when I try:-

Application Error Exception EAccessViolation in module WeatherDisplay.exe at 0281843F

I’m running WD 10.37S99
Any suggestions as to how I sort this out?

Download a fresh full version, reboot computer, re-install WD.

Thanks Dan. All sorted now. Don’t know what caused it, maybe the lousy weather we’ve had today lol.
