I have read about this all over the forums and have tried everything. Every time I open a file in AutoCAD LT 2013 it prompts me with an error "The configured Heidi driver cannot be loaded. Switching to default software driver." Now I really wouldn't mind but I was told it could cause issues down the road. I read that it was a video card issueand I have a new NVIDIA Quadro 4000. However, I have made sure all drivers were installed. I downloaded everything needed to make it up to date and I have Admin rights so that can't be the issue. I am hoping someone knows what I can do to fix the problem. I am also hoping that when fixed it may also help the fact that I have a latency problem in AutoCAD. Every time I box over something to select it a bunch of dash mark boxes show up. I have to zoom in and out to get them to refresh away.
