I also have the same issue with the payroll update crashing the employee center.  I'm not certain the criticality of this problem has been expressed fully to the development team.  Without the ability to get into the payroll area staff cannot be paid.  If you can imagine not getting a paycheck when you are expecting one you might start to understand the severity of this issue. NO ONE over there should be permitted to go home or get paid until this issue is resolved.  The payroll module is one area that CANNOT be allowed to fail.  We need fixes or we need QB to perform payroll for us until the problem is resolved.
