Aatrix ACA Reporting. Has anyone been able to process ACA forms for over 3,000 employees? Aatrix will populate Report 1 of 5 Federal 1094-C but then the system hangs/crashes when trying to populate Report 2 of 5 Federal 1095-C. Have tried on multiple systems. Aatrix worked with a client for 4 hours on Friday but does not have a solution yet.
