FreeFlow Core Server Error

Hello, We are unable to use our FreeFlow Core due to a server error. It had been working fine for several months. It is used quite often. We can access the login but after that it gets stuck on the loading jobs message. Clicking on Workflow Setup generates the following error message. So far, we have shutdown and restarted the workstation several times to no avail. Can anyone help?

Server Error in '/FreeFlowCore' Application.

Re: FreeFlow Core Server Error

You could try restarting the server -- you've probably already done this. Otherwise contact Xerox support to address this.
