Alright, Mohamed!
Please download this zip file: https://animationpaper.com/files/diagnose_ap_opengl_x86.zip
After download, unpack the zip file. Then, double-click the file “diagnose.cmd” to run it. This produces an “ap_diag.txt” file that you must email back to me. (My email is the one you got your activation key from).
We do this to get information on what exact graphics hardware you have. You see, AP is not working properly on your hardware – but we can force AP to use another method for rendering the lines. So after I receive your email with the ap_diag.txt file, I will email a file back to you that you must place in your Animation Paper folder – then it will make AP change method and hopefully it will then work perfectly on your computer.
Best,
Niels
