Hi,
I have placed a question over at Stack Overflow, but it looks like that here is the correct forum to ask,
Link to the question,
http://stackoverflow.com/questions/15554969/google-web-fonts-and-woff/15565988?noredirect=1#15565988
Any ideas what could be the problem?
Thanks in advance.
I'm really sorry Johan, but I have no idea what your question is

Show your @font-face declarations - the one that worked and the one that didn't.
Google sniffs your browser and serves the appropriate webfont for that browser. If it presents ony the WOFF is because that is the webfont format that your browser needs. It will serve other formats when necessary.
I am guessing that your problem is with the location of the webfont.
