Forgive me if this has been discussed before.

I recently upgraded my membership from gold to platinum, in part because I have been using the computer analysis feature extensively, and would like to be able to do it more often, but also because I feel like the 2200 rated computer occasionally misses things.

But when I go to a game I have already analyzed, there's no option to re-analyze the same game with the upgraded computer strength.

Any ideas?

If you got money to spend on a membership than I would recomend getting a chess engine from chessbase their dispicably strong and have excellent analisis (2600++strength) if you can't afford a Rybka 3 or Fritz 11 you can make do with a Fritz 10 from ebay (20 buks) and if you want a Fritz 11 for free download it off internet from any torrent site.
