This particular error was fixed in v2.9.5 of Armadillo (current version is v2.9.8). As noted in other threads of the forum updating to the latest version and performing a full re-publish will fix the problem.
And to quell any uncertainty on the topic, yes I am still active - being a one man shop with an additional full time job, there are occasions when it can take me more time to respond to support requests than I would like.
