I WAS WORKING IN THE SOFTWARE YESTERDAY BUT TODAY IT WILL NOT OPEN AND HAS A MESSAGE "CODE EXECUTION CANNOT PROCEED BECAUSE MFCL40.DLL WAS NOT FOUND. REINSTALLING THE PROGRAM MAY FIX THE PROBLEM". I REINSTALLED AND STILL HAVE THE SAME PROBLEM. HAS ANYONE EXPERIENCED THIS PROBLEM AND RESOLVED IT? CUSTOMER SUPPORT IS NOT OPEN UNTIL MONDAY

My Windows updates are current so that did not work. I downloaded the ProSeriesTool Repair and ran it and that did not fix the issue either. It's difficult not being able to get help on weekends. I guess all I can do is wait until Monday.
