[Question] Hetalia at Comiket

[just-a-fangirl.livejournal.com]

I bought the CD catalogue for Comiket but since my computer does't show Japanese kana or kanji, everything has just come out as random symbols.
I've found the pages listing all the circles selling Hetalia doujinshi, but I don't know where these circles will be located on the day.

I also can't find a map or anything on the Comiket CD...

Can anyone tell me where the circles will be and if we pick up maps at TBS or if it's hidden on my CD somewhere?

Any help would be much appreciated, and I'm sorry for posting this random question here, but I thought someone might know...
