WP Account not active after Membership install

Hello,

I installed the Membership plugin, then install the WPMU Dashboard plugin. When I attempt to login to my WP admin I get the error “Sorry, this account is not active”.

Through ftp I deleted the Membership plugin and was able to login again. But as soon as I re-installed and activated Membership again, I got the same error.

Thanks in advance for any help.

Chris
