Drupal 4->5 site's second language does not show up in google search

Hey everyone, I have run into this particular problem with my drupal site. I installed 2 languages (Russian as the default and English) and everything is turning up fine in search results.

however when I upgraded from drupal 4 to drupal 5, the English version of the site does not show up at all under it's old keywords in google. Both versions show up fine under other search engines, and the Russian version shows up fine during Russian keyword searches, but the English version does not.

any ideas?

Thanks in advance for the help.
