Unable to map file

Well seeing as the other thread died some months ago in 0.9.3, figured start up a new one. I have ran a PackCheck and there was no errors. I deleted Content.ggpk and ran launcher.exe to download it again. First happened on my archer and thought the archer could be bugged, then I made a witch and same thing happened. It's been happening a lot frequently for me and I could not find a solution. I had made sure to let my antivirus and antispyware programs to allow the game.

Not sure if this is needed, but I'll put it just in case.
