Thanks Fabian,
Can I ask you for a favour? Please download this zip file. Unpack the zip. 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.

This info should enable us to send back to you a config file that fixes your blocky lines problem. 🙂
Thanks,
Niels
