i used to have this problem but i moved from vps to a much better dedicated server. a lil more exspensive but it's good now. anyways, make sure you disconnect first from wherever you are then reconnect at the next computer. sometimes, when i would close charts without removing EA's, I saw this happening as well. but now it will automatically disconnect from one compuetr if I connect to another computer with the company i am with
