Super big bug problem, cannot log in :(

So I installed statcounter yesterday, because everything worked fine before I installed the code as a plugin I imagine it has to be the root of the problem…

Anyway, after I log in – I receive four lines

Warning: Cannot modify header information – headers already sent by (output started at /home/bazznor3/public_html/wp-content/plugins/akismet/akismet.php:2) in /home/bazznor3/public_html/wp-login.php on line 9

Warning: Cannot modify header information – headers already sent by (output started at /home/bazznor3/public_html/wp-content/plugins/akismet/akismet.php:2) in /home/bazznor3/public_html/wp-includes/pluggable-functions.php on line 308

And the third and forth lines are same as above, except mention 309, 270.

It seems I am helpless in logging in to fix whatever error there may be in the syntax…anyone got some advice???
