Common::ULong64 returning Signed Integers in iControl

Thanks so much Joe for the feedback - absolutely tried using the casting to unsigned 32 bit integers before posting the question here. Also, in the mean while I have found that by casting them as uint64 variables is a way to get around the errors as listed bellow. Initial testing looks like the returned values are correct when using that type casting however, I'll need to do more analysis before declaring that as a valid work around.
