I'm glad you got your problems figured out. I have the same problem with TU, started reporting two days ago, stating a negative "two late payments on my credit report". I have only one active TL on that report and all of the payments show "ok". I don't know what the deal is there. I haven't bothered with it yet because I have a new account that reported to the other 2 CRA's 3-4 days ago but not yet on TU. Once that updates, I'll see if it corrects my late payment issue.
With their systems being down so much lately and not reporting on time and reporting incorrectly, I really hope they're not correcting the "bumpage" issue - I am so close and don't want to miss out on that!
