Ever since what, ever since the update?
How long have you left it? Since there was a fairly substantial update, it may take a lot longer to update than usual.
well, it takes forever for update to go on. and you know the thing where it ses "Toontown Online" where the status bar is, right? that freezes and I never advance.
If it looks like it's not going to update, try (1)uninstalling Toontown and clear your temporary internet files and cookies, (2)uninstall the Toontown ActiveX control, and (3)manually remove the Toontown references in the registry.
You can try these four steps in order, i.e. try (1), then reinstall, if that doesn't fix it, then do (1)+(2) and reinstall, etc.
