This error message indicates that you have loaded a package with options more than once. Look for two instances of \usepackage[someopt]{algorithm2e} in your preamble (where someopt obviously stands in for whatever options you passed). See http://www.tex.ac.uk/FAQ-optionclash.html, which says:

The error is a complaint about loading a package with options, more than once. LaTeX complains because it has no means of examining the options, rather than because it knows there is a problem. (You may load a package any number of times in a document’s preamble, with no options, and LaTeX will ignore every loading request after the first; but you may only supply options when you first load the package.)

If you type h at the error prompt, you should see more info about the clash.
