"The given key was not present in the dictionary"

I have a report that will not run in "preview" mode in VS 2005. Whereas the
deployed report runs correctly and shows results in about 15 seconds, the
same report (downloaded from the report server) tries to run in preview for
about 60 seconds and then displays "The given key was not present in the
dictionary".
Each of the 4 datasets (3 used for runtime parameter selections and one for
the report's data) run fine.
I've tried some of the other reports developed in SSRS and don't seem to
have this problem elsewhere. (I've not tried all my reports yet though.)
I've recently downloaded and installed .NET 3.0 and the variouls
add-ons/extensions for WCF, WPF and WWF and wonder if this is the root of the
problem.
I've seen some postings related to AJAX and this message but have not yet
downloaded AJAX.
Thanks for any help.
JonThis report had a relatively simple pic chart at the very bottom that
displayed summary data from the prime dataset. The error goes away if I
delete the chart.
(This is the only report I have that includes a chart.)
So, having isolated the problem a little, anyone have an idea what was
happening? This report has been in place for almost 2 years now.
Jon|||why hasn't this been answered. I have the same problem with a chart

Sr. Software Consultant|||Has anyone found anything other than deleting the rdl.data? I copied a report.rdl and pulled it into the same solution so I could try working some objects slightly differently. But now when I try to run the modified report I am getting this message. It seems to be related to the document map and bookmarks, but I can't see anything wrong with them. I've refreshed all the fields on the datasets, I've deleted the rdl.data, but still getting the same error ...
