Tried to register yesterday. It appeared to go well, but no email arrived with a registration code. Tried to register today using a second and a third perfectly valid email address, but the registration form claimed that there was an error in each address.
Maybe a temporary glitch on the license key generator?
Are you checking your email by webmail? Or, you’re saying the avast key registration is returning an error with that email address?
Not using webmail. The registration form rejected two addresses claiming that they contained errors. They didn’t.
