Hi Norm. I`m getting an error message in CVCX and CVData when starting simulations... The error is: "Run-time error '430': Class does not support Automation or does not support expected interface". Can you tell me how I can fix this when you can please? I have version 5 and this started happening right after I updated the software from the website. I know I downloaded the correct one, because the name of the msi starts with "5" (5141b).
