Did you log in before trying to purchase the $29.99 upgrade? If you didn't the system would not see you as owning TI8, thus NOT entitled to the upgrade offer and would switch you to the new customer site. Your best bet now would be to contact sales and explain the problem. Also from what I have seen on postings 2311 is the new German build. There has been some mention of a yet to be released 2310 English build.
