Not able to remove License

I have Rhino 6 license. I used the license to activate Rhino successfully. I went in to the process of validating the license. As part of that I was asked to remove the license from the zoo. I did that from my Rhino account.

Now, When I start Rhino 6, my license is not there.It asks me to enter the license again. when I try to do that. I get the following error.

The problem is, the Rhino does not open so that I can go to options and remove the license. Any ideas / help would be appreciated.

Can anybody please help me with this?
