cannot uninstall program, is needed for boot?

HI, I have xp home. I want to uninstall software for a DSL program, "creative broadband blaster 8012u-v",that did not install correctly. When I tried to delete it a message came up and said I could not uninstall the program because it may be needed to boot. It is not listed in the add, remove file but I do see it in device mgr.with no conflics. When I do a search nothing else shows up. I would like to get some info on what to do to get rid of it. I will not be reinstalling it again because I am going to use another DSL modem.Did searches on other boards but nothing like my problem. Is it possible to use the CD it came with to uninstall it. Please help me if anyone can.
