critical error with typed dataset Key not valid for use in specifiedstate

vs2005 final release, um, i can't open my typed dataset, I am getting
unhelpful error. I could not find any info on it on newsgroups or web
sites. anyone know of a solution? Seems to be something with getting
the connection string, I do seem to have one in my settings file.

of course this is extremely inconvenient because I put a lot of work
into this dataset. this is another reason why I am not convinced of all
these useful wizards and gi tools - yeah they save you time in the short
term, but do they really in the long term? Sorry, I digress. If
someone has a way out of this, please let me know before I redo 5 or so
hours worth of code. Thanks. Here is the error:


One or more errors encountered while loading the designer. The errors

Well, that was real difficult, I just deleted the connection in server
explorer, reconnected and it worked.
