ok well i saw MarkB's issues on crashing but it didn't quite solve my problem...
i play a game and then press alt+tab to minimize out of the game, then i run boxscore extractor just fine and i create the html file without problems..THEN...when i press alt-tab again to return to the game so i can save, i get a black screen, my mouse cursor, and the "mvp2005.exe has had a problem and must close" message. this results in the game crashing and i lose the game i just created the box score with, rendering it useless.
this happens like 40% of the time and i'm gonna try downloading the boxscore extractor again tommorw to see if a later version will fix the problem but any help would be greatly appreciated!
