I am not using AC's interface. I am using Midmark's standalone application. Last week Midmark's tech support helped me resolving this issue. Since AC has Midmark interface, it is using some of Midmark's DLLs. When I installed AC4 it overrided some of Midmark's DLLs and created conflict in Midmark's configuration. This issue was resolved by simply re-registering Midmark's DLLs.
This will be an issue everytime I upgrade my AC. To avoid it, either I have to install two softwares on different machines or follow the procedure as I have mentioned on the top or just use AC's interface. Since I did not want to use two machines and use standalone Midmark's app, I choose the fix I described in my first paragraph.
Thanks.
