Since the most recent update for the origin client I haven't been able to access it at all. Whenever I try to open it it says "only one instance of origin can run at a time. Please check other windows accounts to see if Origin is running." I don't know why this would come up as this is a private and only has one account on it. I don't know whether or not there is a problem with the client or whether I have had my account hacked. I have also tried uninstalling the client and reinstalling but the process will not complete as it says that it is already open. Please help if you know anything about this.
