That is strange and unexpected. I suggest you reach out to Xerox hotline for assistance with that - it should not happen. The license file is in a fixed location and gets read during initialization of the software on the server. Odd.
I re-booted and was able to download the report but Core had lost it's license, something that has been happening when we reboot since the last update.
When I try to access Core Reports it processes for a while and then logs me out for inactivity before it finishes.
When I go to the Administration -> Core Reports it flashes Retreiving Settings for a second, then shows Retreiving Job Reports ... and a spinning wheel. This continues until it logs me out for inactivity later.
I have tried opening a second tab and making sure that is logged in.
Any suggestions that don't delete the log woud be appreciated.
