I'm trying to register my avast! free edition on my Windows Vista 32-bit computer, but avast! won't let me click "Register Now" within the program. Whenever I click the register button, a window pops up that says "retrieving information, please wait" and then just disappears. It doesn't show the form or anything. Just disappears. The register offline button opens the form in the internet, but I have yet to get that e-mail with the key.
