You can now get a free copy of Abbyy's aligner by either writing a review for them or by setting up a SmartCat account. If you already have such an account, write a Support request (click on the button bottom left) with 'Aligner' in the Subject line.

BTW, if Abbyy Aligner doesn't help you (e.g. if you need support for additional languages), there's also LF Aligner - free, open-source and platform-independent. I've used that tool and can only recommend it.
