Longtime ACADE user. Purchased ICAD 10.0 PE+ and was very pleased until I tried to open a second drawing/tab (drawings are .dwg produced in ACADE if that makes a difference). ICAD locked up and I had to give it the three finger salute to get it to shut down. Couldn't get even start page to run until I rebooted the machine. Seems to be getting worse as now I can't open anything, even after rebooting. It is a new laptop and I am going to check the AV setting to see if that could be the cause but any help would be much appreciated.
