newsletter subscribe 2.2.2 can not send e-mail

I installed newsletter subscribe and everythign works good. I can see the layout side box, i have the subscription option under the customers tab now, but when I click send e-mail from the subscription management area or from the tools>send email area I get this error

1267 Illegal mix of collations (latin1_general_ci,IMPLICIT) and (latin1_swedish_ci,IMPLICIT) for operation 'locate'
in:
[SELECT s.email_address as customers_email_address FROM subscribers as s LEFT JOIN configuration as q on LOCATE( s.email_address, q.configuration_value) >= 1 WHERE configuration_key = 'NEWSONLY_SUBSCRIPTION_TEST_GROUP' ]
If you were entering information, press the BACK button in your browser and re-check the information you had entered to be sure you left no blank fields.

Anyone know what this could be?

Is there any chance this could be related to my installation?

definesubscript.php & defineunsubscript.php are supposed to be changed to CHMOD 777 then back to 644. I am 99% sure I did this..but 1% of me can not remember.

No explanation what caused it though. The sql string fixed it so I am happy ;)
