New deployment- investigative reports empty/TLogServer empty

Hi,

I recently had a new deployment done for a customer and a week later the investigative reports showing

If you have just installed reporting tools, the setup program may be preparing your database right now. Please wait 30 minutes and try again. 

it was working but now the above message shows. I did logserver -c and windows says the process crashed. I  re-installed the logserver but still same error.

i ran testlogserver but there are no hits showing, rtm shows fine and filtering works fine but testlogserver showing just accepting connections and no hits as its usually showing.

Any ideas?

thanks!
