After downloading patch, content.ggpk error comes up.

So I downloaded patch and reset my skill points. I got done and did a few runs in Fellshrine, merciless. I logged out and tried to get back on a few hours later and content.ggpk error comes up and game won't run. I checked in my task manager and there are no instances of "client.exe" running. I restarted computer and checked again and still get the error. Don't know if anyone else had that problem, but I'm just going to redownload the game(seeing as that's really the only fix anyways) but I just wanted to bring it to GGG's attention. No harm done and I'm not mad. Love the game and very understanding that this is a beta so bugs and stuff like this are expected. Keep up the good work GGG.

you only have to delete the content.ggpk file as it is said. go to C:/gringing gear games/path of exile and delete that content.ggpk file. then run "client" wich is straight over it. it will automatically download again and allocate ressources like usual. i know since im doing it right now -_-
