Last week, my PC automatically updated it's O/S to Windows 10 Creators Edition. As I have Windows 10 Home, I don't have the option of turning off automatic updates and so it went ahead while I was otherwise occupied for an hour or so away from my PC. Anyway, the update caused numerous problems including some graphics glitches that manifested in Neverwinter as screen freezes and lag-like symptoms. I cured these by using the Windows Recovery option to roll back to my previous installed copy of Windows 10. I now always shut down my PC if I'm going to be away from it for more than 10-15 minutes to ensure the Creators Edition doesn't get reinstalled until after Microsoft fixes the mountain of bugs that come with it.
All well and good, but that isn't the reason for my warning although it is related. Earlier today, to boost my ARC points accumulation options, I installed 'Gigantic'. No problem, it installed smoothly without a hitch and ran quite happily. The problem came when I tried to run Neverwinter. I went to the 'My Games' area on the Arc loader panel and to my surprise the only game still listed was 'Gigantic'. I have several other games installed including Neverwinter and Star Trek Online. None were visible. Running 'Scan For Games' did not find any of them on my hard drive. The directories are all still there but Arc simply isn't recognising any of them. Manually installing them doesn't work either. Arc declares the file to be unrocognised, then goes about asking me to install the game it has just not recognised. As a result, right now, I am in the process of redownloading all 9+GB of Neverwinter so I can play it and may have to do the same for the other games previously available to me through Arc. Fortunately, I have unlimited data downloads available on my broadband package....but it is a right, royal pain in the neck
I cannot know for certain if this is a result of rolling back Windows 10 or of installing 'Gigantic' or some combination of the two but I thought it might be worth mentioning here on the forums just in case others hit the same snags....or want to avoid them in the first place
