I got that once also, but it was with win2k. I don't remember what I went through to get rid of it. Perhaps if you click ok, and depending on what happens, make sure that you have quit all instances of it on your desktop, or maybe even rebooting. I think what I had was an instance running that I had to force quit. I haven't been out to the parallels forum for a while since I had to downgrade to build 1970, but you may find something posted out there. They are a demanding and vocal group on that forum. If you don't find anything (try the search first), then post what you got here and see if anyone there has an answer.
