Just met a mate here (Uruguay) who has an AZ-America box connected to Amazonas and he had to update his configuration on May 28th 2010, so it looks like the keys are out of date.

I wonder if there's anyway of extracting the keys from the .abs files they use to do their updates ? I've looked around but can't find any info. Or any other suggestions about how to get the new keys?

I've been trying the keys posted here with no luck for about a week now in various ways.
