I play counter-strike and have recently run into a problem. I was banned from one specific server because it said I was using a duplicate steam id exploit or something along those lines. I just can not figure out how it happened. I did not attempt to logon from any other computers with my steam account, and havent changed anything on my computer. I was told that it could be an issue with my ISP and figured it was worth looking into. Is there a way that something happened and my IP address was changed, could that have an outcome on the situation. Sorry for all the questions, I am just trying to figure out how/why it happened so I can try to avoid it hapening again. Any help/information is greatly appreciated!
