Guild Wars 2

I’ve had this problem for about a week now. Tried this as a bug report and in the problems thread for the Trading Post forum – I’m hoping someone here can suggest a solution.

I can browse the trading post, but I can’t buy anything on any of my characters. Any attempt to buy directly (I’ve tried 50+ different items, several hundred times) pauses about ten seconds and then gives me the message “Sorry, your order did not match any current listings. Please refresh and try again.” Refreshing shows the same prices available.

Placing a custom order is even less functional – the Trading Post window simply ignores any attempt to click on the “Place Order” button no matter what price or quantity I enter.

Things I’ve tried to solve the problem:
-Restarting the client repeatedly
-Rebooting
-Deleting the Local.dat file from Documents/Guild Wars 2
-Stopping the Awesomium.exe process and restarting the client
-Turning off my firewall and virus protection
-Updating my video drivers
-Loading older versions of Flash (tried this because I remembered there was a Flash update a couple of weeks ago)
-Starting Guild Wars 2 with the -repair argument (8 bad files deleted)
-Running GW2 as an administrator (using Windows 7)

None of this has fixed the problem – I still can’t buy anything on the Trading Post. Any suggestions?

Update: After today’s maintenance on the commerce system, I can use the trading post again.

Unfortunately, most of the things I’ve tried to buy in the last few days (All of which timed out at the time and gave me messages about the transaction not going through) just showed up in the trading post pickup tab, and the gold they cost is now missing.

While I’m happy I can use the Trading Post again, (and the gold isn’t really a huge deal – I can get more) I suspect that anyone else this happens to is going to be quite unhappy about the commerce system processing duplicate transactions days afterwards…
