Hey guys, I have been using Quick Show 3 for 12 months and has been great. Love it. I would keep getting notifications to upgrade and I kept ignoring them. Eventually, I caved in and installed the new version. Ever since then I have been experiencing issues with Virtual DJ sound output which I am guessing it's from quickshow 4 as it has also started to say it requires more power to run properly. I have uninstalled 4 and reinstalled 3 and now it won't let me! It says that the upgrade was MANDATORY. How is this so it it actually worked perfectly? I really need to get Quick Show 3 back on. I don't want to carry two laptops to my gigs. It worked just fine before. Anyone help me there?
