@KAWAiiSONG : Glad you got no errors; me too! Let us know what happens when you move on to Step #4 - #6. @Seegeth : I began testing this last night, but ugh, I made a stupid mistake: Ran DISM tool and System File Checker tools again (no errors). Restarted computer Start testing (problem recurred in just under three hours) Created another local Windows user account (no password; "No" to all privacy settings) Signed into new local Windows account (but forgot to LOG OUT of my main admin Windows account!!) Started Synapse 3; logged into my Razer account; began testing (problem recurred in just over 3hrs) So although I was signed in as "TestUser" on the new local Windows user account I had created, I was ALSO still logged in under my usual admin account. Hours of testing, kind of down the drain. (Also: It didn't take me long to realize (much to my dismay) that all of my game's addons are stored in the Windows username folders. So, with a new Windows user account, I had nooooo addons. And I'm a very heavy addons user, so I missed them terribly, lol. It was kind of brutal playing without them.) So now, I'm back to the drawing board and will begin testing again. I hope to report more later tonight or tomorrow!
