error message keeps popping up.? After removing Vista from my dell xps m1330 laptop, I proceeded to reinstall xps drivers. However I accidentally installed a vista driver, with the id r151522. Even after deleting the file from my computer, an error message continuously pops up. the error message says, "This application has failed to start because Wlanapi.dll was not found. Re-installing the application may fix this problem" I have tried everything I can think of and still cannot get the message from popping up. help please.

i myself would take vista off and piut on xp, xo is better otherwise what i did was just ignore the message.
