How to troubleshoot and fix online problems

[blackwiggle]

Have you tried making a new user account and race under that name?
I hope you had backed up your game save data, there was no reason to delete it as I doubt it has anything to do with your problem.

Are you getting an error code number?, If so what is it?
Or just a cannot connect error message?

There was a problem that was happening to people around a year ago where they couldn't login to online using their proper user name, but they could if they made another user account, it was a real PITA for all concerned and it took SL an absolute age to sort because they couldn't replicate it.
It got to the stage where one of the forum members was giving individual names of the effected to SL so that SL could manually reset those names on the servers, but even that didn't work for long, it finally got fixed around a month before FURY got released with a game update.

I just hope for your sake that this bug hasn't made a return.

Since the sudden influx of new HD players due to the game being free with PS+, a lot of old glitches are starting to reappear, like people coming up on online races as somebody else, which I think might somehow be related to your problem.

What next?
Not the dreaded "Vista Pads" again, that would suck more than a thousand vacuum cleaners
