Lost Blog (after Move to Beta)

You know what...? This blog had ten posts last month; this month - we are not able to log in to add or edit, in fact, we cannot find our blogs at all - the whole blog in each case has just vanished...and we are being allowed to start from scratch using the same URL? Have sent several emails to 'help' after trying all of the standard troubleshooting suggestions at the help center, with negative results. Can anyone help at all....
