The little "update available" window popped up yesterday when I started Madcam. I declined to update immediately but ever since the pop-up appeared, Madcam stopped working. So I downloaded the update. It took many tries to get the file to download completely. For some reason it would terminate before the whole file was received. Anyway, eventually I got the whole file downloaded. After installation the problem persisted. Madcam will load up in Rhino, but after the model is selected for toolpath calculation, no Madcam layers are created
