Many thanks PJSpur and Jonathan for prompt response.
Pressed refresh button a thousand times and finally got the map. At 10.55 green areas for multiple seats still available in corners of East stand. No problems with credit card confirmation. I imagine the processing problem is at the server end. Doubt it has anything to do with connectivity. I'm in the sticks and have probably only got 2MB connectivity at this time of day. I guess the early rush is now over and server is coping more easily.
