I am not positive, but it looks like your license for the aquasuite has expired and you need to purchase an extension, or use the free 2016 5.3 version
Hi Infoseeker,
why do you think that he needs to extend his licence? Aquasuite couldn't find the OCTO and that's the reason why it is giving all this messages.
He has to check his USB conection and to switch off completly his PC, to remove also the power cord from his PC and to keep this for minimum 5 minutes. Then he has to do a full restart. Hopefully, this wil help.
If not, he should contact tomorrow (monday) AC support by mail.
