maybe just your PC too slow or your network is suck- -
I am having this exact same issue now. Installed the game yesterday morning, played it for the whole day. At night i get the popup saying there is an update and that the client will restart. Client closes, patches to 100% and rinse and repeat.
I have verified cache and even redownloaded the game from steam. i just paid $10 for this game and cant even play it properly
