It seems to be a problem affecting everyone Paul, we're trying to figure out what's causing it - but it doesn't help that it seems to be sporadic, and sometimes lets you access the page.
One of the t2w.com email tables got corrupted last night/this morning and it was having a knock on effect to the rest of the site for any logged in members who have a .t2w.com account. Anyone we've now repaired the table, and so everything should be okay again. These things happen, occasionally, unfortunately
No I really don't think they will have gone - (and we take nightly backups anwyay) - but I'll just need to figure what's causing them not to show. I've got the same problem myself, now I've checked - so seems to be affecting us all.
It's not an exact science by any means, but I seem to manage to scrape by (with a little help from my friends!). Anyway, seems like the email table in the database got corrupted too - but once again this has been repaired, and my emails are now all showing up again.
