It's not a lot of information to go on.
Try disabling your firewall (temporarily) and see if the game can connect? It might be blocking access
Try running the game as an administrator? Just in case there's some sort of permissions shenanigans going on.
The fact you are having similar issues with another game suggests its an issue with your computer. Did you make any other changes to it at that time (new software etc?)
The PC Technical Support forums may be able to help you more.
