Hi, I have had an Atik Horizon color camera for a while. I used it a lot with Nebulosity 4 and with the Artemis Capture Program. I had to get a new computer and when I did install the software and the camera it would not work with Nebulosity 4. I works just fine with the native Artemis Capture. All other features of Nebulosity 4 work perfectly. When I click on Atik Universal as I always have it gives me a DLL error. I have reinstalled the camera drivers and Nebulosity 4 to no avail. I have also updated me computer as far as I can. If you have any idea I would be very grateful. I use Nebulosity to focus my camera in live mode. It is a lot easier than using the Artemis software.
