WEMOD won't work

I created an account paid for the pro version, now I downloaded the application and it doesn’t load into my account. Some generic account bs and it wants me to re subscribe to pro again and make a new account. When I try and use the account info I created it says that user name and email is already taken. So is there a login function somewhere that I can’t see? because WEMOD isn’t finding my account period. I don’t understand why there isn’t a login function on the PC app?
Can anyone help me because after trying for an hour this is starting to seem like more trouble than it’s worth.
