I have had Affinity Photo for several months. No major issues. After receiving a promo email I have just purchased Affinity Designer which downloaded and installed OK. On first attempt to open, the app crashed. Tried again, same result. Went back to Affinity Phot and tried to open it and that crashed as well. The Designer install has screwed both apps. I then used the reply in the promo email to advise Serif and ask for assistance. Advised to hold the Control key while opening and when reset menu appears to select all. Tried this with both apps but it does not work with either. HELP!
