Was this on a Windows 8 machine? This may not be related to your other problems. I had a similar message when using the apps in Windows 8 the other day. Not sure if something changed with firewall settings with a Windows update or if it is a problem with the interface between the apps and carrona.org that Windows 8 does not like. I'll have to do some further testing later in the week.
I am still working on getting an official update put together. Unfortunately (in terms of the apps), I was hit with a project at work that demands a lot of my time since we promised a customer three months worth of work would be done in about half that time. I'm enjoying the work, but it means things like forum work and apps work have had to drop off my to do list each day. I should be able to get back to those more in a couple weeks.
