I processed payroll but was about to print checks and my forms were not there, they seemed to be set back to default.  It was strange.  So I tried to copy them over from another company and I got the same results.  So then I manually copied the ...MAS_XXX\Reports\PR_CHECKPRINTING directory over from another company and restarted Sage 100.  The launcher would not open.  I rebooted twice.  Still nothing.  I tried running from another user, another MAS user, nothing.  Is there anything else I can check?
