I cancelled my FlightPlan to change to earlier departure due to WX. In trying to submit the plan the window says "requesting credit count" and has greyed out the continue button, I had one credit remaining but even bought another 20 but can't resolve it. Any clues?

I assume this was resolved via technical support but as far as I'm aware, the issue where requesting credit count never goes away is normally due to a network problem, e.g. SkyDemon is unable to properly talk to its server.
