i have windows 7. awhile ago, i downloaded aimersoft dvd creator. i used it once, burned the dvd, and it played. after my trial an out, i uninstalled the program. ever since then, my windows dvd maker won't burn a dvd. it always gives me the error message, "cannot create the dvd. an error occured when burning the dvd."

any help? i already tried chaging the burn speed. i still got the error message.

i can burn cd's just fine.
