Hi Brian,
On the original report make a copy of it and then open it in CR Designer. And/Change the SQL and then start removing objects and whole sections to see if you can find the source of the problem. It could be some object needs to be updated or it is possibly corrupt and the RPT file itself has been corrupted somehow, no way to "fix" it.
If you try to change anything else can you save it?
DJ, what you posted makes no sense...
