activation not valid

i got an upgrade to wavelab 7 from wavelab studio 6 today, i’ve tried to put the activation code in but it’s saying that theres a problem or ive mis-entered the code, i’ve tried several times double and treble checking the letters and numbers and it won’t work, i know that there was an issue with wavelab 6 activation codes has there been any issues with 7.
i also got cubase 6 upgrade today which went through without a hitch.
i have emailed steinberg but no response yet.

Please check your PM´s.
