My Michael 4.cr2 has 5,19 MB - the readme says something about 5,2 MB ...
Ideas?

Haven't tried it yet but my M4 cr2 is 5.21mb. Possibly been updated ?

Edit - just tried it and it unencoded perfectly against my Michael 4 cr2. Definitely check for an update to yours. According to my downloads I downloaded an updated version on 11th February 2010.
