Since files are going missing maybe your anti-virus is removing them. Try disabling it and playing the game after you do a fresh install.
Try not to install anything custom made unless you know for a fact that it's compatible with the newer version.Have you tried restarting your router, logging into another computer / different browser perhaps?After re-downloading the game, have you tried downloading the game using another method? Ran the game as an administrator? ( might be some missing / bad files ).Sorry if these come off as confusing, just throwing ideas out there.
