Despite the fact I am also new to Modicon and I am not sure I can help you, I will tell you that you have provided insufficient information about your problem. It may sounds trivial, but sometimes everything depends on small details and they do matter. So, tell us what operation system you are using, the error(s) you get, what happens, etc...
