You may well have reached your limit for the month of November.
Your auctions are listed for 3 days? As an aside, are you aware that these will cost you a non refundable listing fee of 35p each listing. 3 day listings is an optional listing upgrade.
Auctions when manually relisted count towards your 300 free listings a month, if these are being relisted constantly, you may have reached a selling limit. Check this on your homepage under monthly limits.
Personally, I think your items have a ceiling level of price so can be listed for that price in a Buy it Now format. Buy it Now items relist automatically every 30 days if they do no sell, and those automatic relists do not count towards your free 300 listing limit.
Check your monthly limit.
