error sound bug

i have a bug on my animate:
error sound is sounding for no reason, at the press of different assential keys(mainly but not only- the space bar), resulting in an in ability to work unless you turn your speakers off!
i googled it but found nothing. in my local animation group on FB some people are familair with it but had no real solution to the problem. needles to say that turning speakers off is not a solution either...
what do i do? 😞
