Data download locking up

[Fred_in_oz]

I seem to have a bit of a glitch with Cumulus in that when I open it up it says that it is "downloading data - please wait" as per normal but it doesn't actually download any data it just hangs.
I thought it may have been my USB cable but I open easy weather and it downloads all of its data and updates ok so the USB appears ok.
I had a bit of a look at the diags files and it says something about bad startup blocks.
Can you have alook and maybe point me in the right direction to sort it out.
Cheers
Fred

Cumulus looks for the first two bytes to be 55 AA, which say that the station has been initialised, but your first byte is zero.

15/08/2011 23:10:55.765 : EWUSB: EW startup data line 01 00 AA 00 00 00 00 10 08

You had some sort of problem at 22:24

15/08/2011 22:20:00.937 : Writing today.ini, LastUpdateTime = 15/08/2011 10:20:00 PM raindaystart = 78.9000015258789 rain counter = 81.3000030517578
15/08/2011 22:24:14.164 : 10:24:14 PM EWUSB: HidControl Device Unplug
15/08/2011 22:24:14.164 : VID = 1941 PID = 8021
15/08/2011 22:24:14.179 : EWUSB: HidControl Device Removal
15/08/2011 22:24:14.179 : VID = 1941 PID = 8021
15/08/2011 22:24:14.429 : EWUSB: HidControl Device Removal
15/08/2011 22:24:14.429 : VID = 1941 PID = 8021

and now the station isn't behaving as Cumulus expects.

I'm afraid I don't know how you solve this; I guess a reset of the station may be required - or you could try using EW to re-set the logger interval. Any idea what happened at 22:24?

I had left cumulus running earlier in the day, around 13:30 and about 22:30 was when I got back to it and thats when cumulus was locked up.
The kids may well have been on the computer earlier and done something.
.
I have loaded the latest beta of 1.9.2 (as it appeared to fix somebodys lockup issue before) but it has made no difference. The diags still look the same.
Time to reset the weather station!!!
