I had a Windows update on Wednesday morning and now Bobcad seems to hang up. I can open and run small files, but not the large 2+3 files I was working on. They take a long time to open and now the software times out at exactly 60 seconds and shuts down. I tried increasing the timeout in the registry, but makes no difference. Anyone else having a problem or know how to fix? I've tried multiple files on multiple computers all with the same results. 60 seconds of loading and Bobcad shuts down. Please help. Thanks.
