I am having an issue with installing Password Manager - it will not accept my new activation code, so naturally I went to make contact with the support team and tried to sign in using the "sign in " tab https://helpcenter.trendmicro.com/signin-saml_1. Unfortunately, I get an invalid page error and a suggestion that I may have typed in the wrong address!!!!!. Hard to sort out my problem when this web link doesn't work. Might I  suggest that it is fixed

Hi, 

Please activate the serial number first on our activation portal: Trend Micro Account
Once done, you may try to install the Password Manager and sign in your Trend Micro Account.
