I Can connect sometimes to Valhalla, but when it doesn't let me my internet goes down. The strange thing is, nothing like this has everhappened with any other game only MTA. I Don't know why it screws up the Modem, and EVERYONE'S Internet in my house.

Every time I connect to Valhalla gaming, I seem to get "Failed client verification" And I have No mods installed, and I've tried extremely hard to google this problem up, but I find no solution every time so I finally decided to post. The weird part is, everyone in my house loses connection when this happens, I portforwarded my router, and it still happens, and we have to restart the router every time is happens and my family gets rather mad at me. Any Ideas anyone?
