Curves not showing up in files

When opening my files, curves are not showing up in any file. Nor am I able to create any. The same files are opeining fine on other laptops so the problem is not with the file. I can select the curves by the layer, but nothing gets highlighted, only in the taskbar does it say that items were selected. The only thing in the file that I can see is text. I updated my drivers, so that wasn’t the problem.

Hello- please check the Display panel - (Panels menu) and make sure curves are set to display.

If that does not sort it out, please run the SystemInfo command in Rhino and copy/paste the results here.
