Re: Auction House Bug
@TheBigMadCowwhat error message do you get? I hope it is not related to a (unjustified) ban.
my first guess would be trying to do a power cycle. I've read that power cycling your PS might solve issues regarding the connection to EA servers and the issue you describe seems to be a connection issue.
how to do it (taken from a post by @EA_Aljo): >>> unplug your modem, router and console. After 2 minutes plug in the modem and router. Let them come back online completely. Then plug in your console and start it up. <<<
my second guess: maybe your lineup causes this error. sometimes there is something corrupted saved in the background of your lineup. creating a new lineup (e.g. by using the 'generate best OVR' option) and rebuilding your existing lineup might solve this issue (if it is caused by the lineup).
hope that helps. good luck!
