I saw two Supporter plugins in my wordpress 3.0.1 install and went to "Network Deactivate"

I saw two Supporter plugins in my wordpress 3.0.1 install and went to "Network Deactivate" one of them.. Got the below error

Fatal error: Call to undefined function is_supporter() in /home2/wtgnowco/public_html/recoveryspeaks/wp-content/plugins/widget-supporter-badge.php on line 69

Now I cannot access my blog.

I hate to take the Supporter plug-in out manually from ftp, but not sure what to do here.

Please advise--
Dave
