I'm sure one of the previous suggestions will sort out the problem. However, I thought I'd add my 2 cents.
I recall years ago, when Works started getting loaded on every computer shipped in NA, that the Works icon was very similar, if not completely identical, to the Word icon.
I recall that I had a very cynical reaction to that, assuming that M$ was hoping to cash in on the incompatibility between Works and M$Office. You know how it goes, give the free piece of **** and when they find out that it's compatible with bugger all, they'll come running for the full office suite.
You may ultimately have to find a new/create your own icon. Of course, the best course of action would be to expose your user to the type of derision scorn and brutal demeaning that I have found to be useful, when a user sticks with a piece of software that is limitlessly bad.
