hi, i just bought a Lexar JumpDrive (512 MB) which the package says is compatible with ME. When i insert it into the USB drive and click on the Lexar icon, a window pops up saying "a required .dll file MFC42u.dll was not found. This is my father's computer--I have a Mac and am a novice when it comes to dealing with Windows. Given this, any advice would be greatly appreciated! Thanks
