Lightroom Classic is asking for sign in everytime and does not work

Hello,

Suddenly every time i try to open Lightroom or Photoshop it keeps asking me to sign into my account(which it was already in auto sign in) and then I enter the account info and doesn't work, so I try going into the account in my browser, I sign in there and it works fine but now says that Lightroom and Photoshop that I've been using for 3 years are not install when they are obviously install. 

Something is very wrong here, like if the information in the account wasn't right and very different than 

my desktop. 

So basically even known I've been a paying(and current) subscriber for a couple of years now, i can't use 

Lightroom or Photoshop anymore.

Any idea on what to do??

i really need to use them since I'm a photographer and NEED to work on my photos.

Any help will be greatly appreciate it.

Thanks.
