Adobe Acrobat Pro Sign in pop up issue

Hello,

I have been running into issues with installing Adobe Pro, requiring me to sign in whenever I open adobe pro.  So I do just that, I sign in, but I would end up with the message with the website telling me to close my browser and continue with the application. 

But that is not the case I try to open it and I still get the sign in pop up. 

I am working on mutliple workstations and installing adobe on all of them with one email account, is that a problem? Do I need a seperate email address for all workstations? 
I am also using a serial number for these installs.
