Unable to find Team management Functions

Apparently you have two accounts. This one you posted with, with zero credits and the one you have made the team with, which does have credits and which you crunch with.

Easily found out.
First off, with the account you posted this with, go to your account and log out.

Then go back to your account. You should have the option to log in here, with email address/password and with the authenticator key. We're going to do the second one.

Navigate to your BOINC directory on your computer. Seeing that you use Windows XP and assuming you didn't change the default directory, it's in c:\\program files\\boinc

Now open up account_einstein.phys.uwm.edu.xml and find and copy the number between the tags.

Paste this number in the Authenticator key log in option on your account.
Press OK. And you'll be logged in on the account you are crunching with.
You can then also post with that one, and by going to that account's 'your account', change the team's info.
