As the ingame turbine point purchasing wasn't working for me, I purchased some points through the DDO market and received a code.
Following the instructions on the "Maintenance Complete" post, I logged into myaccount.turbine.com and attempted to redeem them through the product key section.
Unfortunately, all that happens when I hit submit is that the page refreshes and the code I just entered has gone, there are no instructions to follow despite what the forum post says.
This is a little frustrating after the rather lengthy maintenance, especially as its now all supposed to be working.
