I just received my Certificate and password from LoTW, and also subscribed to QRZ's XML Data-level membership. When I tried to "enable" the LoTW functionality (By using the LoTW "Setup" button on the Settings page), I get an error saying something about my LoTW password / Certificate are not valid. I know this is not correct since I have used the Certificate and Password to successfully Log-In to the LoTW account. Anyone else experienced this same issue ? If so, how do I correct it?

Please help.
I didn't find the right solution from the Internet.
