The original data was lost when the forums crashed in May 2008. Since then, we all created ID's on the new temporary forum, then they recovered the old data and merged it with the temporary forum to create what we have now... so basically you should have 2 ID's. The one you used here, and your prior one (with "imported" in front of it).
An admin can merge the two ID's for you so that your original posts will be linked and counted correctly. Sadly, I do not remember the address to e-mail your request to. I am sure someone else here can advise you on it.
Safe Journeys!
