hi

What I did is in VS2005, right click the report name, change it and then rebuilt it, deploy it. And then go to Report Manager, I can see the new one, but when i run it, it shows this error:

Execution 'fralkj45eeyh0te5opip4455' cannot be found

what does this mean, does anybody know how to fix it?
thanks.

It should be fine after changing the name.
I delete it from report manager, and re-build, delopy to the report server, then it works fine.
