Easyjet boarding pass - unable to print/download

Can't find a more suitable place to post this thread.

I have a Macbookpro operating Mac OSX 10.6.4 and I use the Safari browser.

I use Easyjet a lot and have had no problem printing/downloading boarding passes - until recently. The two last times I've travelled (within the past 2 weeks) I have ben unable to print or download. My partner has no problem using her conventional laptop with the same booking reference. Does anyone have any idea what the problem could be?

Thanks in anticipation.
