I bought Affiinity Design (for Windows 10) yesterday. When I launched the soft, a error message told that something goes wrong with the "pen driver" (I have a Huion GT220 that was working quite well untill ... yesterday !).
As my "pen-screen-tablet" didn't want anymore to recognize correctly the pencil, I uninstalled Affinity application (in fact, we don't really know whether it is correctly uninstalled... in my opinion, none), but now the scrren doesn't work (I know that Huion Drivers are quite sensitive and ask to be "alone" to recognize the pencil... I had few monthes ago, to start from a fresh intallation of windows to get a stable configuration). I'm quite angry because Artrage, Adobe or ClipStudio Paint were working without create any issue ! So the Affinity Message that ask us to contact the hardware manufacturer seems to be quite irresponsible...
