I played a game on Tygem recently that I wanted to review, but I can't seem to find a way to download a sgf file anywhere. In my user info I can find the game I want, but when I click on it it just pulls up a blank goban that canot even be edited.

Maybe people with the free English client cannot access their games after the fact?

You'll find the games in the "C:\Users\YourSessionName\AppData\Local\VirtualStore\Program Files (x86)\TygemGlobal\Games" path in Win7 (at least that's where my games are).
The games are in the .gib format so you'll have to convert them into sgf (i use multigo for that).
Hope that helps !

Thanks, I was able to find the folder where the files are kept, but for whatever reason, the game I was looking for was not present. I guess it can't be helped.

In tygem client you need to save this game first. -> List of personal games->Double click->game window->save. Or Games(top icon on the right side)->personal games->list of games-->double click. You get big game window and in the lower right->menu->sav game. Sorry if this is like tutorial for a complete newbie but you never know

Just in case it helps: I have a perl script for converting .gib into .sgf, at http://alum.mit.edu/www/eric_backus/.
