sheetcam.com

Just now moving from a trial version to a licensed version and also upgraded to newest version of SheetCam. On launching, the popup window announcing SheetCam doesn't close. Then others that I open to make selections won't close, they just get overlaid with others. Trying to set Sheetcam up for working with my new plasma table, so plasma is my focus right now. I can't open a drawing or even a dxf file I had opened prior in my trial evaluation. It seems to hang with a small popup saying checking air centers. That's as far as things go. Even a window opened to look at my computer settings hangs and won't close until I close SheetCam. I'm getting nowhere with it, any ideas what I'm doing wrong? Didn't have this problem in my earlier evaluation, just now after adding the license. That evaluation period was a year ago though, just don't recall none of this I'm seeing today.

Thanks
