After upgrade to Reporting 5.8 existing reports no longer work.

We recently upgraded to Reporting 5.8 and now our existing reports fail to run properly. We get this error message:

{

"$type": "JobQuit",

"kind": "Run"

}

Error: 0: Unexpected Error: System.InvalidOperationException: Operation is not valid due to the current state of the object.

Anyone had issues after upgrading versions?

Thanks,
