I am using a MacBook Air, OSX 10.14.4 and tried to change my English Beta Trial version to a German one. I went to Affinity homepage, selected a new download with "German Flag" - hoping to get the "German" version, installed this download, overwrote the existing version, and after opening, it was the English version again. So I tried to reset the parameter ram (three times), deinistalled completely the existing version with "CleanMyMac" (deinstall function), loaded again the "German" version from AffinityHomepage, installed it once more and after opening, it was the English one again.... What I have downloaded was # 1.7.0.293
