you both missed what i said, this is not the first time i have used pre numbered labels , never had a problem till today
Ah, sorry - I didn't realize you'd used them successfully before.
I think I've seen other reports of this problem, now that I understand, but I just tried searching the forums and couldn't track it down. If I recall correctly, someone else who was familiar with using prenums ran into a situation such as you describe - but I don't know if it was tracked down to a particular bug, or if the problem went away by itself after a short time.
If you remember approximately what time you tried to activate your prenums and got new BCIDs instead, you could use the "contact us" link to submit a bug report to the support team; include the prenumbered BCIDs you entered, and the new BCIDs that were generated instead, along with the usual configuration info (your operating system and browser). Oh, and include the steps you took - that is, were you using the "journal entry" menu item from the "home" tab, or typing the BCID directly into the big "GO!" box at the top of the page, or some other link? I do know that there have been cases where one entry-point for a particular function worked better (for some configurations, anyway) than another one, even though they *should* do the same thing.
Sorry this isn't much help. The problem might go away on its own, which is almost as frustrating as having it stick around - the "sporadic" bugs are a pain to solve. If you try again later, and if it's still happening - and if you're up for a little debugging - perhaps you could try a different browser, or even a different computer, just to see if that changes things.
