Board Thread:Off Topic/@comment-30249349-20180109140458

So first off, I know this should be in the Technical Support board, but for some stupid reason I can't get on it. So, i post this in the off topic board instead. I have Geometry Dash lite, Geometry Dash World, Geometry Dash Meltdown, and Geometry Dash Subzero, and I decided to download Geometry Dash full version using an online Chinese appstore. However, after two weeks, this happened to me: when I try to open my Geometry Dash, it always says "unable to verify app developer" and even if Ive tried to verify my app developer I still get the message. PLEASE help me! Or I'm quitting!
