System.FormatException: The string was not recognized as a valid DateTime. There is a unknown word starting at index 0.

(Sorry, I posted this as a reply to Calendar Cell but it''s really not related to that)

I just started getting this message on 5/4/05! I''m not parsing and before
this, my program worked just fine. Here''s a posting I put on another site
in desparation:

Greetings,

I don''t know how long ago this conversation took place, but am desperate
for help with the same problem. Up until two days ago, my code for
inserting a record into a table worked fine. Update still works, but on
insert, I am getting this dialog box now:

System.FormatException: The string was not recognized as a valid DateTime.
There is a unknown word starting at index 0

It''s driving me crazy. Mostly because this has worked fine until now.
There are four dates (though I removed TimeStamp to try to fix) and I have
tried everything!

One important thing to note is that my product is completely in English,
having nothing to do with other timezones or anything like that.

Anyway, I don''t know if anyone can (or has time to) help. Just thought I''d
try and ask. :)

Here''s some more information:

(Save table just executes the stored proc called InsertSystemParameter)
