Question : disappearing site - a challenging question

I have a site that has been live since 1 march.   it has been optimised sufficiently well for it to be
no 1 on yahoo and 2 on bing for the the main keyword phrase.
it was until six weeks ago around no 8 on google.
now the site has disappeared from google.
i have checked through all the checks on webmaster and it seems to be being crawled o.k; and there are no errors
under search queries the graph drops to zero on 31 may and has remained there ever since.
the site is shown to have over 6,000 backlinks which I know is incorrect.   It has about 20 genuine backlinks.
on google analytics the traffic, on the moving monthly average, keeps falling by about 15% each day.
Where Search Engines accounted for 80% of traffic in April, today the figure is 51% for june.
I have tried changing the content of the home page, less than a week ago so it is clearly too soon to see if this has any effect.
There is another problem/clue.   I originally optimised the site for keyword  phrase xxxx    yyyy, which according to adwords keyword tool was attracting 800,000 searches a month with about 12 million pages so it was not bad going getting the rankings I have.
however now the phrase, for some reason, does not even come up in the keywrod tool.
I am mystified because the url is a very good one being eight years old and I just do not know what to do to restore this site in google.
any suggestins please

Answer : disappearing site - a challenging question

"The tables and the View live on the same server."  I misread this the first time.  Yes, they're on the same server (physical box), but not on the same database. That's what's causing your problems in Crystal Reports. When you join objects from disparate datasources (even if it's the same type of database residing on the same physical machine) you have severe limitations and potential performance issues.

In order to resolve these issues, the best option is to consolidate the various datasources into a single place for Crystal Reports to query.  Here are a couple of options:

1)  Create the view on the same database as the tables, but leave it pointing to the original database.  As far as Crystal Reports is concerned, the tables and view will be on the same database, so there's no issue - this would be my first choice, personally.  Unless you're not allowed to create views on the UDT4 database, you shouldn't have any problems.

2)  Create a SQl Command that reference both the tables and the view.  Since the command will be pointed to a single datasource, you'll eliminate performance issues.

On a side note, WOW that's a lot of vehicles to pass.  Is that the result of selecting every vehicle in the picklist?
